Ingredients You’ll Need
- Let’s gather our ingredients. This recipe is a beautiful lesson in how a few simple, quality components can create something truly special. The key is balancing the starch of the potatoes with the moisture and flavor of the spinach and dairy.
- Yukon Gold potatoes: 2.5 pounds, peeled and cubed. I swear by Yukon Golds for mashed potatoes—their naturally buttery flavor and creamy texture when cooked are unmatched. Russets can work but tend to be more gluey.
- Kosher salt: 1 tablespoon for the boiling water, plus more for seasoning. Using salted water is the first step to seasoning the potatoes from the inside out.
- Fresh baby spinach: 5 ounces (about 5 packed cups). Fresh spinach wilts down perfectly and purées smoothly. I don’t recommend frozen here, as it retains too much water and can make the potatoes soggy.
- Unsalted butter: 4 tablespoons, divided. Butter is non-negotiable for richness and flavor. We use some to cook the spinach and the rest to enrich the potatoes.
- Garlic: 2 cloves, minced. Sautéing the garlic gently unlocks its sweetness and removes any harsh raw bite.
- Cream cheese: 4 ounces, at room temperature. This is my secret weapon for ultra-creamy, stable mashed potatoes that reheat beautifully. The slight tang also balances the richness.
- Heavy cream or whole milk: 1/2 cup, warmed. Warm dairy absorbs into the hot potato starch better than cold, preventing a gummy texture.
- Freshly grated nutmeg: 1/4 teaspoon (optional). Trust me, a tiny pinch of nutmeg is a classic pairing with spinach and adds a wonderful warmth that enhances all the other flavors.
- Black pepper: 1/2 teaspoon, freshly ground.

Kitchen Equipment Needed
You don’t need any fancy gadgets, but a couple of tools will make the process smoother and give you a better final texture.
- Large pot: For boiling the potatoes.
- Colander: To drain the potatoes thoroughly.
- Potato ricer or food mill: This is the single best tool for achieving perfectly smooth, lump-free mashed potatoes. If you don’t have one, a standard potato masher will work—just mash thoroughly.
- Large skillet or Dutch oven: For wilting the spinach.
- Food processor or high-powered blender: Essential for turning the wilted spinach into a silky-smooth purée. A regular blender works better than an immersion blender here.
- Rubber spatula: For folding the green purée into the potatoes gently.
How to Make Sally’s Spinach Mashed Potatoes Recipe
Step 1: Cook the Potatoes to Perfection
Start by placing your peeled and cubed potatoes in a large pot. Always cover them with cold water and add the tablespoon of salt—starting in cold water ensures they cook evenly. Bring to a boil, then reduce to a steady simmer.
Cook for 15-18 minutes, or until a fork slides into a chunk with no resistance. Believe me, overcooking here makes them waterlogged. Drain them well in a colander, then return them to the hot, dry pot for a minute.
Letting them steam dry is a pro tip that prevents watery mashed potatoes.
Step 2: Wilt and Purée the Spinach
While the potatoes cook, let’s handle the spinach. In your large skillet, melt one tablespoon of butter over medium heat. Add the minced garlic and cook just until fragrant—about 30 seconds.
You don’t want it to brown. Now, add all the fresh spinach. It will look like a mountain, but it wilts down dramatically.
Toss it with the garlic butter and a pinch of salt for 2-3 minutes until it’s completely wilted, dark green, and has released its moisture. Tip from me: transfer it all, including any liquid, to your food processor.
Step 3: Create a Vibrant Green Purée
Process the wilted spinach and garlic until it’s a completely smooth, vibrant green paste. This step is crucial for that beautiful color and seamless texture. If the mixture is having trouble moving, add a single tablespoon of the warm cream from your measured amount to help it along.
You shouldn’t see any flecks or pieces. Set this emerald purée aside while you work on the potatoes.
Step 4: Mash and Cream the Potatoes
Now for the satisfying part. If you have a ricer or food mill, pass the hot, dry potatoes through it back into the pot. This gives you the fluffiest, smoothest base.
If mashing by hand, do so thoroughly until no large lumps remain. Add the remaining 3 tablespoons of butter, the room-temperature cream cheese, and the warmed cream or milk. Stir and mash until the mixture is uniformly smooth, creamy, and luxurious.
The warmth of the potatoes will melt everything together beautifully.
Step 5: Combine, Season, and Serve
Gently fold the smooth spinach purée into the creamy potato base using a rubber spatula. Stir until the color is even and stunning. Now, season with the black pepper, nutmeg, and additional salt to taste.
I always do this at the end so I can balance the seasoning perfectly. For the final touch, stir the mixture over very low heat for just a minute or two to ensure everything is piping hot. Serve immediately in a warm bowl with an extra pat of butter melting on top.
Step back and admire your gorgeous, flavorful creation.
A few insights from my years in professional kitchens will guarantee your success every time.
- Potato Choice is Key: Yukon Gold potatoes have a waxier texture and more buttery flavor than Russets, which are starchier. This means they mash up creamier and are less likely to become gluey if over-mixed.
- The Purée Principle: Thoroughly puréeing the spinach is non-negotiable. Any remaining leaf fragments will create a less appealing texture. The goal is to infuse color and flavor, not add roughage.
- Temperature Control: Always add warm dairy to hot potatoes. Adding cold cream or milk cools the starch suddenly and can lead to a gummy, thick consistency as the starches tighten up.
- Avoid the Blender for Potatoes: Never purée cooked potatoes in a blender or food processor. The rapid blades will rupture the starch cells and create a glue-like, elastic texture. A ricer or masher is the way to go.
- Season in Layers: Salting the boiling water seasons the potatoes from within. Seasoning again after combining all elements allows you to balance the final dish perfectly.
Recipe Variations & Customizations
- This recipe is wonderfully adaptable. Here are some tested variations to make it your own.
- Garlic Lover’s Twist: Roast a whole head of garlic and squeeze the sweet, soft cloves into the potatoes along with the spinach purée for a deeper, caramelized garlic flavor.
- Herb-Infused: Stir in 2 tablespoons of finely chopped fresh herbs like chives, parsley, or dill along with the spinach purée for a garden-fresh brightness.
- Dairy-Free/Vegan: Use vegan butter, plain unsweetened oat milk or canned coconut milk (full-fat for creaminess), and a vegan cream cheese alternative. The flavor will be different but still delicious.
- Extra Cheesy: Fold in 1/2 cup of freshly grated Parmesan or Pecorino Romano cheese after adding the spinach purée. The salty, umami punch is incredible.
- Loaded Spinach Potatoes: Top the finished dish with crispy chopped bacon, shredded cheddar cheese, and sliced green onions for a “loaded” potato experience.
- Lemon Zest Brightness: Add the finely grated zest of one lemon to the spinach while wilting. The citrus note cuts through the richness beautifully.
- Spicy Kick: Add a pinch of red pepper flakes or a dash of hot sauce to the spinach while it cooks for a subtle warmth.
What to Serve With This Recipe
These vibrant mashed potatoes are a versatile side that pairs beautifully with a wide range of mains. Their rich flavor and stunning color make them ideal for special occasions.
For a classic holiday spread, serve them alongside a juicy herb-roasted turkey, a standing rib roast with horseradish cream, or a honey-glazed ham. The potatoes’ color and savoriness complement rich meats perfectly. For everyday dinners, they are fantastic with simple pan-seared chicken breasts, oven-baked meatloaf, or pan-fried pork chops.
The potatoes add a gourmet touch to a simple meal. For a vegetarian feast, pair them with a creamy mushroom Wellington or stuffed acorn squash. Beverage-wise, a crisp Chardonnay, a light Pinot Noir, or even a hard cider would be lovely matches.
Storage & Make-Ahead Instructions
- This recipe is a fantastic make-ahead option, especially for busy holidays.
- Refrigeration: Store cooled mashed potatoes in an airtight container in the refrigerator for up to 3 days. The color may darken slightly but the flavor will still be great.
- Reheating: The best method is to reheat gently in a saucepan over low heat, stirring frequently and adding a splash of milk or cream to loosen them up. You can also reheat in a covered dish in the oven at 325°F (160°C) for 20-25 minutes, stirring once halfway.
- Freezing: I don’t recommend freezing this version. Potatoes and dairy can separate and become grainy upon thawing and reheating.
- Make-Ahead Strategy: You can complete the entire recipe 1 day ahead. Transfer to a baking dish, smooth the top, and dot with extra butter. Cover and refrigerate. Reheat, covered with foil, in a 350°F (175°C) oven for 30-40 minutes until hot throughout.
Frequently Asked Questions
Q: Can I use frozen spinach instead of fresh?
A: I don’t recommend it for this specific recipe. Frozen spinach retains a lot of water, even when thoroughly squeezed. That excess moisture can make your mashed potatoes soggy and dilute the flavor.
Fresh spinach wilts perfectly and purées smoothly for the best texture and vibrant color.
Q: My mashed potatoes turned out gummy. What happened?
A: This is almost always due to over-mixing. When hot potatoes are stirred too vigorously, the starch molecules break down and release a sticky gel. Use a ricer for initial smoothing, fold ingredients gently, and avoid using electric mixers or blenders on the cooked potatoes.
Q: Can I make these potatoes dairy-free?
A: Absolutely. Use a high-fat vegan butter and a plain, unsweetened non-dairy milk like oat or soy. For the cream cheese component, a plain vegan cream cheese alternative works well.
The flavor profile will change but will still be creamy and delicious.
Q: How can I get the brightest green color?
A: Two tips: First, don’t overcook the spinach—just wilt it until it’s bright green and soft. Second, purée it while it’s still warm. Prolonged heat and acid (like lemon juice added too early) can cause the green chlorophyll to dull.
Q: Is it okay to leave the potato skins on?
A: Yes, for a more rustic texture and added fiber, you can scrub the potatoes well and leave the skins on. Yukon Gold skins are thin and pleasant. Just note that the final color will be a more muted, flecked green rather than a solid vibrant hue.
Q: Can I prepare the spinach purée ahead of time?
A: Yes, you can wilt and purée the spinach up to a day in advance. Store it in an airtight container in the refrigerator. Let it come to room temperature or warm it slightly before folding into the hot potatoes for easier incorporation.
Q: What’s the purpose of the nutmeg?
A: Nutmeg is a classic, subtle pairing with spinach and creamy dishes. It adds a warm, aromatic depth that enhances the other flavors without tasting distinctly like “nutmeg.” A little goes a very long way.

Ingredients
Instructions
-
Place the peeled and cubed potatoes in a large pot. Cover with cold water by 1 inch and add 1 tablespoon of kosher salt. Bring to a boil over high heat, then reduce to a simmer. Cook for 15-18 minutes, or until the potatoes are fork-tender. Drain well in a colander and return them to the hot, dry pot for a minute to steam off excess moisture.
-
While the potatoes cook, wilt the spinach. In a large skillet or Dutch oven, melt 1 tablespoon of butter over medium heat. Add the minced garlic and cook for 30 seconds until fragrant. Add all the fresh spinach and a pinch of salt. Cook, tossing frequently, for 2-3 minutes until completely wilted and bright green. Transfer the spinach and garlic to a food processor or blender.
-
Purée the spinach mixture until completely smooth. This is key for a vibrant green color without leafy bits. Add 1 tablespoon of the warm cream or milk to help it blend if needed. Set the vibrant green purée aside.
-
Mash the potatoes. Pass the hot, drained potatoes through a ricer or food mill back into the pot for the smoothest texture. If you don't have one, use a standard potato masher. Add the remaining 3 tablespoons of butter, the room-temperature cream cheese, and the warm cream. Mash or stir until smooth and creamy.
-
Combine and season. Fold the smooth spinach purée into the creamy mashed potatoes until evenly incorporated. Season with the nutmeg, black pepper, and additional salt to taste.
