How to Make Stuffed Shells (Step-by-Step)

Making this delicious Stuffed Shells recipe is easier than you think. Here’s how to make them at home step by step:

Start by peeling the mushrooms, then rinse and cut them into small pieces.

Sauté mushrooms on high heat for 5 minutes or so. The mushrooms will release some water. As soon as the water evaporates, reduce the heat to medium and sauté for a couple more minutes.

Set aside and let the mushrooms cool until ready for use.

Next, shred all the cheese and mix it together. Cover it with plastic food wrap and refrigerate until ready for use.

After that, measure out all the Italian sausage ingredients, mix them together, and set aside until ready for use.

To save time, I cook the pasta while I sauté the meat. Boil the jumbo pasta shells according to the package’s label instructions in a large pot. When it’s done, drain and rinse the pasta with cold water. This prevents the pasta from becoming slimy and sticky.

Cover the pasta with a lid. This will prevent it from drying out while you work on the meat.

Add 2 tablespoons of olive oil to a large frying pan, then add the ground beef. Sauté the beef on high heat until it releases water and sizzles.

Reduce the heat to medium and add mixed seasonings. Sauté for 5 minutes and stir occasionally.

Add and mix in roasted garlic pasta sauce and tomato sauce. Sauté for 3 more minutes. Set aside and let it cool. The meat should be warm, not hot, when adding cheese.

Combine the sautéed and cooled beef, sautéed and cooled mushrooms, diced yellow pepper, cottage cheese, egg, and half of the shredded cheese mixture in a large bowl.

Reserve and refrigerate the other half for topping stuffed shells. Mix everything carefully; do not mash it. 

Preheat your oven to 350 degrees F. Stuff each large shell with about ⅓ cup of filling using a spoon and line them in an oven-safe baking dish or casserole dish.

Cover the pan with aluminum foil and bake for 40 minutes at 350°F. Remove from the oven, remove the aluminum foil, top the shells with the reserved cheese, and bake uncovered for another 10 minutes. I personally needed 2 (10 X 13”) pans for 60 jumbo shells.

I cooked one right away and saved one in the fridge, covered with plastic food wrap, for the next day. You may also freeze these shells. If freezing, you will need to freeze some shredded cheese separately.

Defrosting will not be necessary; just extend the cooking time for about 10 minutes. Leave the cheese on the countertop, and it should thaw out while the shells are baking.

Remove from the oven, cover the pan with the foil used earlier, and let it cool for 15 minutes before serving with garlic bread or a side salad. 

Your delicious Stuffed Shells recipe is ready to be served!

Tips for Making the Best Stuffed Shells Ever

• Drain the Cottage Cheese: Drain cottage cheese well to remove excess moisture and keep the filling creamy without becoming watery.
• Add Fresh Herbs: Garnish the baked shells with fresh parsley or basil for a burst of color and fresh flavor.
• Let Them Rest: Allow the stuffed shells to rest for a few minutes after baking. This helps the filling set and makes them easier to serve.

Recipe Variation Ideas for Stuffed Shells

• Seafood Stuffed Shells: Replace ground beef with cooked crab, shrimp, or lobster. Add lemon zest, fresh basil, or parsley for a bright seafood flavor.
• Mediterranean Stuffed Shells: Swap in feta or ricotta and add sun-dried tomatoes, Kalamata olives, artichokes, oregano, and basil. Finish with olive oil or tzatziki.
• Spicy Stuffed Shells: Add chopped jalapeños or red pepper flakes to the filling, or use spicy marinara or arrabbiata sauce for extra heat.
• Vegetarian Stuffed Shells: Skip the beef and add sautéed spinach, bell peppers, zucchini, and onions. For extra protein, try tofu or plant-based meat alternatives.

How to Store Leftover Stuffed Shells

• Refrigerate: Let the stuffed shells cool completely, then store them in an airtight container or cover tightly with plastic wrap. Refrigerate for up to 4 days.
• Freeze: Freeze stuffed shells for up to 3 months in a freezer-safe container.
• Reheat: Bake refrigerated or thawed shells at 350°F for about 20 minutes, or until heated through.
