Make It Your Way
I love sharing this gratin as is, but it’s also a fantastic base to get creative with. Feel free to swap cheeses or add your favorite extras to make it truly your own.
- Vegetarian Variation: Skip the pancetta and toss in toasted walnuts or mushrooms for an earthy crunch.
- Cheese Swap: If you don’t have Gruyère, Swiss or fontina work beautifully in this recipe.
- Seasonal Twist: In spring, fresh baby spinach could replace frozen—just sauté lightly to remove moisture.
- Spicy Kick: Add a pinch of red pepper flakes with the onions if you like a little heat.
Step-by-Step: How I Make Spinach Gratin with Pancetta and Triple Cheese Recipe
Step 1: Crisp the Pancetta to Perfection
Start by cooking the diced pancetta over medium heat until it’s crispy and golden. This renders out that delicious fat, which you’ll use to cook your onions and garlic. Pro tip: Use a slotted spoon to transfer pancetta to paper towels, so it stays crisp and not greasy in the gratin. Don’t rush this step—crispy pancetta makes a massive difference in texture and flavor.
Step 2: Build the Flavor Base
In the same skillet with pancetta fat, sauté diced sweet onions and minced garlic with a pinch of salt and pepper until softened and fragrant. This usually takes about 5 minutes. Stir often so nothing sticks. This is the base that gives your béchamel a rich, savory backbone.
Step 3: Make the Creamy Béchamel Sauce
Sprinkle the flour over the softened onions and stir to cook the flour for 2 to 3 minutes—it should turn golden and smell nutty. Slowly whisk in the milk and heavy cream, ensuring you pour gradually to avoid lumps. Keep stirring until the sauce thickens and can coat the back of a spoon. Add the nutmeg now—it’s subtle but elevates the sauce wonderfully.
Step 4: Add Cheese and Spinach
Reduce heat to low and add the Parmesan by handfuls, stirring until melted. Then, squeeze any excess liquid from the frozen spinach (tip: wrap it in a clean dish towel and squeeze tight!) before stirring it into the sauce. Finish by mixing in half of your grated Gruyère, then taste for seasoning and add salt and pepper as needed.
Step 5: Bake Until Golden and Bubbling
Transfer the mixture into your baking dish and sprinkle the remaining Gruyère on top. Bake in a 425°F preheated oven for 25 to 30 minutes until the top is bubbly and the cheese forms a gorgeous golden crust. Serve it up warm and watch your guests swoon.
Pro Tips for Making Spinach Gratin with Pancetta and Triple Cheese Recipe
- Don’t Skip Squeezing the Spinach: Excess moisture leads to a watery gratin—wring it out thoroughly for rich, creamy texture.
- Use Quality Cheese: The flavor depth largely comes from using sharp Parmesan and authentic Gruyère, so try not to substitute with pre-shredded blends.
- Watch Your Roux Closely: Stay attentive when cooking the flour-onion roux to prevent burning and keep the sauce silky smooth.
- Bake Until Just Bubbling: Overbaking can dry out the gratin, so pull it from the oven the moment it’s golden and bubbling.
How to Serve Spinach Gratin with Pancetta and Triple Cheese Recipe
Garnishes
I usually finish my gratin with a light sprinkle of freshly cracked black pepper and a few shavings of Parmesan right before serving for that extra wow factor. Fresh thyme leaves also add a lovely herbaceous note if you have any around.
Side Dishes
This gratin pairs beautifully with roasted chicken or pork loin. For a lighter meal, serve alongside a crisp green salad with lemon vinaigrette. When I make it for holidays, I often add crusty bread for sopping up all the cheesy goodness.
Creative Ways to Present
For special occasions, I love serving individual portions in small ramekins—each guest gets their own golden, bubbling gratin to dig into. You can also sprinkle crispy pancetta pieces on top just before serving for an elevated look and extra crunch.
Make Ahead and Storage
Storing Leftovers
After enjoying your meal, wrap leftovers tightly with plastic wrap or move them into an airtight container and keep them in the fridge. They last wonderfully for up to 3 days, and the flavors actually deepen overnight.
Freezing
This gratin freezes well if you prep the mixture but haven’t baked it yet—just cover tightly and freeze for up to 2 months. I always thaw overnight in the fridge before baking to maintain the creamy texture and even cooking.
Reheating
Reheat leftovers in the oven at 350°F covered with foil to keep moisture in—about 20 minutes should do, depending on the amount. Avoid microwaving if you want to preserve the creamy texture and crispy top.
FAQs
-
Can I make this Spinach Gratin with Pancetta and Triple Cheese Recipe dairy-free?
Yes! To make it dairy-free, you can substitute the milk and cream with unsweetened almond or cashew milk and use dairy-free cheese alternatives. You might need to experiment slightly with thickening the sauce using cornstarch instead of flour for the roux to get the right consistency.
-
Is it okay to use fresh spinach instead of frozen?
Absolutely. If you’re using fresh spinach, sauté it first until wilted and make sure to squeeze out all excess water. The key is to avoid any watery mixture that could make the gratin soggy.
-
Can I prepare the gratin fully in advance?
Definitely. You can make the full gratin, then refrigerate it covered. When you’re ready to serve, let it sit at room temperature for 30 minutes before baking as directed. This is a great trick for entertaining without last-minute stress.
-
What’s the best baking dish to use?
A 9×9 or 6×10 inch baking dish works perfectly. You can also use an oven-safe skillet if you want to go straight from stove to oven for less cleanup.

- 3 tablespoons Baker’s Corner All-Purpose Flour
- Kosher salt and pepper, to taste
- 1/4 teaspoon Stonemill Ground Nutmeg
Instructions
- Preheat oven Preheat your oven to 425 degrees Fahrenheit to prepare for baking the gratin.
- Cook pancetta In a large skillet over medium heat, cook the diced pancetta, stirring often until the fat renders and the pancetta becomes crispy. Use a slotted spoon to remove it and place it on a paper towel to drain excess grease.
- Sauté aromatics Keep the skillet on medium heat and add the diced onion, minced garlic, and a pinch of kosher salt and pepper. Cook for about 5 minutes, stirring often, until the onions soften.
- Make roux Stir in the flour to the onion mixture to create a roux. Cook, stirring for 2 to 3 minutes until the mixture is golden, fragrant, and nutty.
- Add liquids Slowly whisk in the whole milk while continuously stirring. Then pour in the heavy cream while stirring. Continue to cook for 5 to 6 minutes, stirring often, until the mixture thickens to a sauce that coats the back of a spoon.
- Flavor sauce Add the ground nutmeg and reduce the heat to low. Stir in the parmesan cheese gradually, one handful at a time, stirring until completely melted.
- Prepare spinach Remove the spinach from the packaging and squeeze out any excess liquid using a dish towel. Add the spinach to the béchamel sauce and mix well. Turn off the heat and stir in half a cup of the shredded Gruyere cheese. Taste and adjust salt and pepper if needed.
- Assemble and bake Transfer the spinach mixture to a 9×9 or 6×10 inch baking dish (or keep it in an oven-safe skillet). Sprinkle the remaining Gruyere cheese evenly over the top. Bake in the preheated oven for 25 to 30 minutes until the gratin is bubbly and has a golden brown crust.
- Serve Remove from the oven and serve immediately for best flavor and texture.
- Make ahead tips To prepare ahead, either fully bake and later reheat covered with foil in a low oven until warmed through, or prepare the mixture and store it in the refrigerator until 30 minutes before baking. Let sit at room temperature for 30 minutes prior to baking as instructed.
Notes
- Squeezing out the excess liquid from frozen spinach is crucial to prevent the gratin from becoming watery.
- Gruyere cheese provides a rich, nutty flavor but can be substituted with Swiss cheese if unavailable.
- Using freshly grated parmesan cheese melts better and adds superior flavor compared to pre-grated varieties.
- If you prefer a vegetarian version, omit the pancetta or replace it with smoked mushrooms for a smoky flavor.
- Make sure to let the dish rest a few minutes after baking for easier serving.
