Creamy Garlic Mushroom Stuffed Shells have become my go-to dish whenever I want something truly comforting yet elegant for my family or guests. The plush ricotta and earthy mushrooms tucked inside tender pasta shells deliver creamy flavor in every bite. A velvety Alfredo sauce ties it all together, making an irresistibly cozy vegetarian main that always earns rave reviews at our table.
Ever since I surprised my parents with these shells on their anniversary, it has been requested for countless celebrations and cozy Sundays. The aroma alone always gets everyone flocking to the kitchen.
Ingredients
- Jumbo pasta shells: You want shells that are unbroken and sturdy so they hold the filling without falling apart Try to pick pasta from a reliable brand for best results
- Ricotta cheese: Choose whole milk ricotta for maximum creaminess This creates the soft luscious filling
- Grated Parmesan cheese: Adds sharpness and nutty flavor Freshly grated Parmesan melts best and packs more taste
- Cooked mushrooms: I like to chop and sauté a mix of cremini and button mushrooms until deeply browned They deliver earthy body and savory notes
- Egg: A farm fresh egg binds the filling so it stays intact inside each shell
- Garlic powder: This packs a mellow depth without overpowering the cheese Always check for freshness in your spice jar
- Salt: Season both the filling and pasta water with sea salt for the brightest flavor
- Black pepper: Adds just enough subtle heat Opt for coarsely cracked pepper if you like more bite
- Alfredo sauce: Go for a creamy jarred version you trust or make it from scratch if you are feeling ambitious It acts as both the sauce base and gooey topping
- Shredded mozzarella cheese: This melts beautifully on top delivering the perfect finish Choose part skim or whole milk based on how stretchy you want it
Step-by-Step Instructions
- Cook the Pasta Shells:
- Boil your jumbo shells according to the package instructions until just al dente Drain them and lay on a tray to cool so they do not stick together or tear during stuffing
- Make the Filling:
- Mix together the ricotta Parmesan cooked mushrooms beaten egg garlic powder salt and black pepper in a large bowl Blend thoroughly until the mixture is creamy and mushrooms are evenly distributed
- Prepare the Baking Dish:
- Set your oven to 375 degrees Fahrenheit and get a baking dish ready Spread one cup of Alfredo sauce in an even layer on the bottom to prevent sticking and create a saucy foundation
- Stuff and Arrange the Shells:
- Use a spoon or small spatula to gently fill each shell with a generous scoop of the creamy mushroom mixture Arrange stuffed shells closely together in the prepared dish so they support each other and hold shape
- Top with Sauce and Cheese:
- Pour the remaining Alfredo sauce evenly over the filled shells Sprinkle the shredded mozzarella over everything to guarantee a bubbly golden crown when baked
- Bake to Perfection:
- Cover the dish tightly with foil and bake for 25 minutes to warm through and melt the cheese Remove the foil then bake uncovered another 10 minutes so the top turns golden and just starts to brown

That earthy mushroom flavor against the creamy ricotta is what truly elevates this pasta for me I still remember my little nephew grinning ear to ear when he got the first gooey cheesy serving at our holiday table Pure comfort food joy
