Ingredients You’ll Need

This recipe is all about layers of flavor and texture, so each ingredient plays a starring role—from the salty pancetta to the nutty cheeses and the tender spinach. I always recommend using good quality cheeses and fresh garlic to really make it sing.

• Appleton Farms Diced Pancetta: Pancetta offers deep, porky flavor and a crispy texture that elevates this gratin.
• Sweet Onion: Adds natural sweetness that balances the saltiness of the pancetta and cheeses.
• Garlic Cloves: Fresh garlic gives a fragrant, savory backdrop—don’t skip it!
• Kosher Salt and Pepper: Essential seasonings to bring out every flavor; taste as you go.
• All-Purpose Flour: Makes the roux that thickens the creamy sauce without any lumps.
• Organic Chopped Frozen Spinach: Convenient and consistent—remember to squeeze out excess moisture to avoid a watery gratin.
• Whole Milk: Provides creaminess without heaviness; I prefer whole milk for the best mouthfeel.
• Heavy Whipping Cream: Adds richness and silkiness to the béchamel sauce.
• Ground Nutmeg: A pinch enhances the cheesy sauce with a subtle warm spice.
• Parmesan Cheese: Sharp, nutty, and perfect for folding into the sauce.
• Gruyère Cheese: Melts beautifully and adds a creamy, slightly sweet flavor that pairs perfectly.

Variations

I love how this creamy spinach gratin feels so cozy as is, but sometimes I like to tweak it depending on my mood or what I have on hand. Feel free to make it your own — experimenting is half the fun!

• Vegetarian Version: Just skip the pancetta and add a bit more Gruyère for richness; my friends who don’t eat pork still rave about it.
• Spice It Up: Add a pinch of cayenne or some crushed red pepper flakes in the sauce if you want a subtle kick—I’ve done this, and it’s a lovely surprise.
• Different Greens: Swap spinach for kale or Swiss chard if you want a sturdier green; just cook them a bit longer to soften.
• Use Fresh Spinach: You can use fresh spinach instead of frozen. Just sauté it first and squeeze out excess water before adding—the flavor is fantastic!

How to Make Creamy Spinach Gratin with Pancetta, Gruyère, and Parmesan Recipe

Step 1: Crisp the Pancetta

Start by heating a large skillet over medium heat and adding your diced pancetta. I love how this cooks down and renders its fat, giving you those crispy, flavorful bits that add such a great texture contrast. Stir often and watch carefully to avoid burning. Once crispy, scoop it out with a slotted spoon and drain on paper towels. Don’t toss that flavorful fat—you’ll use the same skillet for the next steps, which adds so much flavor to your onions and sauce!

Step 2: Prepare the Aromatics and Roux

Using the same skillet with the pancetta fat, add diced onions, minced garlic, and a pinch of salt and pepper. Cook gently over medium heat until the onions soften and become translucent, about 5 minutes. Stir often so nothing sticks or browns too fast. Next, sprinkle in the flour to create a roux—it’ll start to smell nutty and golden after 2 to 3 minutes, which means you’re on the right track. This step is vital for that perfectly thick, creamy sauce.

Step 3: Stir in Milk, Cream, and Seasonings

Slowly pour in your cold whole milk while whisking continuously—this helps keep the sauce smooth and lump-free. Then add the heavy cream and keep stirring as the sauce thickens (about 5 to 6 minutes). You’re aiming for a consistency that coats the back of a spoon. Don’t forget to stir in a pinch of ground nutmeg here; it adds such a cozy warmth to the dish.

Step 4: Melt in the Parmesan Cheese

Lower the heat and start folding in the grated Parmesan, a handful at a time, stirring until each batch fully melts into the sauce. This step gives your béchamel that unmistakable cheesy depth. If you skip this slow melting, the sauce might become grainy, so patience here really pays off.

Step 5: Prepare and Add the Spinach

Thaw your frozen chopped spinach and then squeeze out any excess moisture with a clean dish towel or cheesecloth. This is one of those tips I discovered after a watery baked gratin ruined a holiday meal—don’t skip it! Add the spinach into the cheese sauce, stirring well. Then fold in half of the grated Gruyère cheese. Give it a quick taste for salt and pepper now, because once it’s baked, it’s too late to adjust.

Step 6: Bake Until Golden and Bubbling

Transfer the creamy spinach mixture to a baking dish—something around 9×9 or 6×10 inches works great. Sprinkle the remaining Gruyère evenly on top. Pop it into a 425°F oven for 25 to 30 minutes or until it’s bubbly and golden brown on the edges. I love watching that cheese bubble and caramelize—it’s like the best part of baking therapy.

Serve immediately so everyone can enjoy it at its melty, gooey best!

How to Serve Creamy Spinach Gratin with Pancetta, Gruyère, and Parmesan Recipe

Garnishes

I usually sprinkle a little fresh chopped parsley or thyme on top right before serving. It adds a pop of color and a fresh note that cuts through the richness. Sometimes I even add a few crunchy toasted breadcrumbs for texture. My family absolutely loves that little extra crunch!

Side Dishes

This gratin pairs wonderfully with roasted chicken, grilled steak, or even a simple lemony baked fish. I especially love serving it alongside herb-roasted potatoes or a crisp green salad for a balanced meal. It’s also fantastic as part of a holiday spread.

Creative Ways to Present

For special occasions, I sometimes bake this in individual ramekins and top each with a small sprig of thyme or a single crisp pancetta piece. It makes for a charming presentation that’s both personal and indulgent. Another fun idea is layering it in a shallow cast-iron skillet to serve family-style right from the oven.

Make Ahead and Storage

Storing Leftovers

I usually store leftovers in an airtight container in the refrigerator for up to 3 days. My trick is to cover it tightly so that the cheese and sauce stay creamy and don’t dry out. When you reheat, it still tastes like it’s fresh from the oven.

Freezing

While I prefer eating this fresh, I’ve frozen it successfully. Just let it cool completely, then freeze in a freezer-safe dish. When you’re ready, thaw overnight in the fridge and bake at 350°F, covered with foil until heated through. It retains most of its creamy texture, though the crispy top is best fresh.

Reheating

To reheat, I cover the gratin with foil and warm it in a 350°F oven for about 15-20 minutes, checking that it’s heated through without drying out. Avoid microwaving if you can—it tends to separate the sauce and dull the flavors.
