Ingredients You’ll Need

This Creamy Mushroom Pasta Bake Recipe brings together simple ingredients that effortlessly complement each other. You’ll want fresh, high-quality mushrooms and cheeses to really nail those rich, comforting flavors. A heads-up: don’t rush on the roasting step! It’s a game changer.

• Baby Bella mushrooms: Their meaty texture and earthiness make them the perfect star for this dish.
• Kosher salt and black pepper: Essential to season layers full of flavor; kosher salt is less intense, so it’s easier to control seasoning.
• Fresh thyme: Adds a subtle herbaceous note that elevates the mushrooms beautifully.
• Olive oil: Use good quality for roasting mushrooms and enhancing flavor.
• Rigatoni: The ridges and tube shape help hold the creamy sauce and cheese perfectly.
• Ricotta: Brings smooth, creamy texture that balances the richness.
• Fontina cheese: Melts wonderfully and adds an indulgent, buttery flavor.
• Heavy cream: For that luscious sauce base.
• Baby spinach: Adds freshness and a pop of color; steaming before mixing keeps it tender.
• Garlic paste: Garlic is a must here for savory depth; paste blends seamlessly.
• Parmigiano Reggiano: Adds salty, nutty brilliance, split between the mix and topping.
• Nutmeg (optional): Just a pinch brings warmth and subtle complexity.

Variations

I love customizing this Creamy Mushroom Pasta Bake Recipe depending on the season and what’s in my fridge. You can easily tweak it to suit your taste or dietary needs—feel free to make it your own!

• Vegetarian protein boost: I sometimes add cooked lentils or sautéed tofu cubes to make it more filling without meat.
• Different greens: Swap baby spinach for kale or Swiss chard—just make sure to steam and drain them well before mixing.
• Cheese swaps: If you can’t find fontina, gruyere or mozzarella work great too for that gooey melt.
• Make it lighter: Use half-and-half instead of heavy cream and skip the ricotta for a lighter bake, though it won’t be quite as rich.

How to Make Creamy Mushroom Pasta Bake Recipe

Step 1: Roast the Mushrooms Until Golden and Flavorful

Preheat your oven to 450°F and position a rack on the second-lowest level. This high heat is key to roasting the mushrooms instead of steaming them. Toss the quartered baby Bella mushrooms with olive oil, fresh thyme, kosher salt, and black pepper—don’t skimp on the seasoning here. Spread them out evenly on a baking sheet; overcrowding will cause them to steam, and you want that concentrated browning. Roast for about 15-20 minutes until deeply browned and fragrant. This step gives your bake that next-level earthy richness.

Step 2: Cook Rigatoni ‘Very Al Dente’

While the mushrooms roast, bring a large pot of salted water to a boil—don’t forget the 2 tablespoons of kosher salt for flavor. Add your rigatoni and cook it about 2 minutes less than package directions. The pasta will finish cooking more in the oven, so you want it just shy of fully tender. Trust me, this little trick guarantees you won’t end up with mushy pasta.

Step 3: Prepare the Spinach and Mix the Filling

Quickly steam your baby spinach for about 30 seconds just until wilted, then drain it thoroughly. Once cool enough, squeeze out as much moisture as you can—this prevents a watery bake—and roughly chop. In a large bowl, combine the spinach with nutmeg (if using), heavy cream, ricotta, fontina, ¼ cup Parmigiano Reggiano, garlic paste, and the roasted mushrooms. Mix gently but thoroughly to ensure even distribution of flavors.

Step 4: Combine Pasta and Bake

Add the cooked rigatoni to the mushroom and cheese mixture and toss everything together. Give it a quick taste to see if you need any extra salt or pepper—you’ll want that balance just right before baking. Transfer the whole mixture into a 9 x 13-inch baking dish. Sprinkle the remaining Parmigiano Reggiano evenly on top. Cover the dish with parchment paper, then foil—this double cover prevents sticking and keeps everything moist. Bake for 15 minutes on the middle rack.

Step 5: Uncover and Finish Baking Until Golden

After 15 minutes, carefully remove the covering and return the bake to the oven for another 5 minutes. The top should turn a beautiful golden color. For an extra touch of caramelization, I like to broil it for 1-2 minutes at the end, but keep a close eye so it doesn’t burn. Once out of the oven, let it rest for 15 minutes so the cheese can settle perfectly—this step makes it easier to serve and enhances the texture.

How to Serve Creamy Mushroom Pasta Bake Recipe

Garnishes

I love topping this pasta bake with a sprinkling of fresh chopped parsley or extra Parmigiano Reggiano for brightness and contrast. A drizzle of good olive oil or a few cracks of fresh black pepper right before serving really amps up the flavor. If you’re feeling fancy, a few toasted pine nuts add unexpected crunch and nutty depth.

Side Dishes

To keep things balanced, I often serve this creamy pasta bake with a simple green salad dressed in lemon vinaigrette or roasted vegetables like asparagus or brussels sprouts. Garlic bread or a warm crusty baguette are perfect for soaking up any leftover sauce—though honestly, that often disappears before it hits the table!

Creative Ways to Present

For special occasions, I like to make individual portions in small ramekins or mini cast iron skillets—makes for a darling presentation and keeps the cheese perfectly gooey. You could also sprinkle fresh herbs like thyme or basil right before serving to add pops of color and aroma. This recipe shines on a rustic wooden board paired with wine for casual dinner parties.

Make Ahead and Storage

Storing Leftovers

I usually let leftovers cool to room temperature, then store them tightly covered in the fridge for up to 3 days. The flavors actually deepen after a day, making for a delicious quick lunch or dinner. Just be sure to reheat gently to keep the cheese creamy.

Freezing

This recipe freezes wonderfully! I portion it into airtight containers and freeze for up to 2 months. When you’re ready, thaw overnight in the fridge before reheating. The texture stays smooth and the flavors hold up beautifully.

Reheating

For best results, reheat leftover pasta bake in the oven at 350°F covered with foil to retain moisture, about 15-20 minutes depending on quantity. You can also microwave single portions, but adding a splash of cream or water before heating prevents it from drying out.
