- 1 pound potato gnocchi: The tender base that soaks up all the creamy, savory flavors.

- 1/4 teaspoon crushed red pepper flakes (optional): For those who love a touch of heat.
- 3/4 cup heavy cream: Creates the rich, velvety sauce that ties everything together.
- 1/2 cup vegetable broth: Lightens the cream and adds depth to the sauce.

How to Make Baked Gnocchi with Brussels Sprouts and Leeks Recipe
Step 1: Prepare and Sauté the Vegetables
Start by heating the olive oil in a large skillet over medium heat. Add the halved Brussels sprouts first and cook them until they start to brown and soften, about 5 to 6 minutes. The caramelization at this stage builds a deep, nutty flavor essential for the dish. Next, toss in the thinly sliced leeks and minced garlic. Sauté everything together for another 3 to 4 minutes until the leeks become tender and fragrant. Season the veggies with salt, black pepper, and crushed red pepper flakes if you want that extra hint of spice. This quick sauté beautifully balances the natural sweetness of leeks with the slightly bitter bite of Brussels sprouts.
Step 2: Cook the Gnocchi
Meanwhile, bring a pot of salted water to a boil and cook the potato gnocchi following the package directions—usually just a few minutes until they float to the surface. This gentle boil ensures the gnocchi are delightfully pillowy and ready to soak up the creamy sauce. Once cooked, drain them carefully to keep that perfect tender texture intact.
Step 3: Mix the Creamy Sauce
In a large bowl, whisk together the heavy cream, vegetable broth, Dijon mustard, thyme, and half of the grated Parmesan cheese. This mixture will become the luscious sauce that envelopes the gnocchi and vegetables, giving each bite that dreamy creamy richness. The mustard and thyme add just the right amount of complexity without overpowering the delicate flavors.
Step 4: Combine Everything and Prepare for Baking
Add the cooked gnocchi and sautéed vegetables into the cream sauce bowl and gently toss to coat every piece evenly. Transfer this creamy blend into your prepared baking dish. Sprinkle the shredded mozzarella cheese and the remaining Parmesan cheese on top, adding those golden melty layers we all love. Dot the surface with small pieces of butter, which helps with browning and adds extra richness during baking.
Step 5: Bake to Perfection
Pop the dish into your preheated oven at 400°F and bake for 20 to 25 minutes or until the top is bubbly and golden brown. The baking process melds all the flavors, thickens the sauce, and creates a slightly crispy top layer that contrasts beautifully with the tender gnocchi underneath. Once out of the oven, let it rest for a few minutes to settle before serving. This step helps the sauce thicken just a bit, making it even more irresistible.
How to Serve Baked Gnocchi with Brussels Sprouts and Leeks Recipe

Garnishes
To elevate your Baked Gnocchi with Brussels Sprouts and Leeks Recipe, sprinkle freshly chopped parsley or basil for a pop of color and freshness. A light drizzle of balsamic glaze or a few shavings of extra Parmesan right before serving add those finishing touches that make the dish feel truly special.
Side Dishes
This creamy gnocchi bake pairs beautifully with crisp, refreshing sides like a simple green salad dressed with lemon vinaigrette, or roasted chicken for a heartier meal. The sides should complement but not compete with the rich, comforting main dish, letting the baked gnocchi shine as the star.
Creative Ways to Present
For a rustic yet elegant presentation, serve the baked gnocchi straight from the baking dish, allowing everyone to dig in family-style. Or, plate individual portions topped with an additional sprinkle of fresh herbs and a crack of black pepper. For a more festive look, add edible flowers or microgreens to brighten the plates visually.
Make Ahead and Storage
Storing Leftovers
Any leftovers from your Baked Gnocchi with Brussels Sprouts and Leeks Recipe can be stored in an airtight container in the refrigerator for up to three days. The creamy sauce might thicken in the fridge, but a little gentle reheating will bring it right back to its luscious consistency.
Freezing
This recipe freezes well if you want to prepare it ahead of time. Place cooled portions in freezer-safe containers or bags and freeze for up to two months. Thaw overnight in the refrigerator before reheating for best results. Keep in mind that the texture may be slightly softer after freezing due to the cream sauce.
Reheating
Reheat leftovers gently in the oven at 350°F until warmed through, which keeps the texture crispier than a microwave. If using a microwave, add a splash of cream or broth to loosen up the sauce and cover the dish to heat evenly without drying out.
