Beef Shells Casserole: just the name conjures up images of cozy family dinners and comforting, cheesy goodness, doesn’t it? Forget complicated weeknight meals; this recipe is your new best friend! Imagine tender ground beef nestled amongst perfectly cooked pasta shells, all swimming in a creamy, flavorful sauce and blanketed with melted cheese. It’s a symphony of textures and tastes that will have everyone asking for seconds.

While the exact origins of Beef Shells Casserole are a bit hazy, its roots are firmly planted in the American tradition of resourceful home cooking. Casseroles, in general, became incredibly popular in the mid-20th century as families sought affordable and convenient ways to feed a crowd. They were a perfect way to use up leftovers and create a hearty, satisfying meal with minimal effort. This particular variation, with its ground beef and pasta, likely evolved from Italian-American influences, blending the love of pasta with the practicality of casserole cooking.

What makes this dish so universally loved? It’s the perfect combination of simplicity and deliciousness. The creamy sauce is rich and comforting, the beef adds a savory depth, and the pasta provides a satisfying chew. Plus, it’s incredibly versatile! You can easily customize it with your favorite vegetables or cheeses. But most importantly, it’s a dish that brings people together. So, gather your ingredients, preheat your oven, and get ready to experience the joy of a truly classic Beef Shells Casserole!

Beef Shells Casserole this Recipe

Ingredients:

  • 1 pound ground beef
  • 1 large onion, chopped
  • 2 cloves garlic, minced
  • 1 (28 ounce) can crushed tomatoes
  • 1 (15 ounce) can tomato sauce
  • 1 (6 ounce) can tomato paste
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 pound jumbo pasta shells
  • 15 ounces ricotta cheese
  • 1/2 cup grated Parmesan cheese
  • 1 egg, lightly beaten
  • 1/4 cup chopped fresh parsley
  • 2 cups shredded mozzarella cheese
  • 2 tablespoons olive oil

Preparing the Meat Sauce:

Okay, let’s get started with the heart of this casserole – the meat sauce! This is where all the delicious flavors begin to meld together. Trust me, taking your time with this step will make a huge difference in the final result.

  1. Brown the Ground Beef: Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until it’s browned all over. Make sure to drain off any excess grease. Nobody wants a greasy casserole!
  2. Sauté the Aromatics: Add the chopped onion to the skillet and cook until softened, about 5-7 minutes. You want the onion to be translucent and slightly sweet. Then, add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as it can become bitter.
  3. Simmer the Sauce: Stir in the crushed tomatoes, tomato sauce, tomato paste, oregano, basil, salt, and pepper. Bring the sauce to a simmer, then reduce the heat to low, cover, and let it simmer for at least 30 minutes, or even longer if you have the time. The longer it simmers, the richer and more flavorful it will become. I usually let mine simmer for an hour or more, stirring occasionally to prevent sticking.

Cooking the Pasta Shells:

While the meat sauce is simmering away, let’s get the pasta shells cooked. It’s important to cook them al dente, as they will continue to cook in the oven.

  1. Boil the Pasta: Bring a large pot of salted water to a rolling boil. Add the jumbo pasta shells and cook according to the package directions, but reduce the cooking time by about 2 minutes. You want them to be slightly firm to the bite.
  2. Drain and Rinse: Drain the pasta shells in a colander and rinse them with cold water to stop the cooking process. This also helps to prevent them from sticking together. Set them aside to cool slightly.

Preparing the Ricotta Filling:

Now for the creamy, cheesy goodness that will fill those shells! This ricotta filling is super easy to make, and it adds a wonderful texture and flavor to the casserole.

  1. Combine the Ingredients: In a medium bowl, combine the ricotta cheese, Parmesan cheese, egg, and parsley. Mix well until everything is evenly combined. The egg helps to bind the filling together, and the parsley adds a touch of freshness.
  2. Season to Taste: Season the ricotta filling with a pinch of salt and pepper to taste. You can also add a little bit of garlic powder or Italian seasoning if you like.

Assembling the Casserole:

Alright, the moment we’ve been waiting for – assembling the casserole! This is where all our hard work comes together to create a beautiful and delicious dish.

  1. Preheat the Oven: Preheat your oven to 375°F (190°C).
  2. Grease the Baking Dish: Lightly grease a 9×13 inch baking dish with cooking spray or olive oil. This will prevent the casserole from sticking to the bottom.
  3. Fill the Shells: Using a spoon or a small cookie scoop, carefully fill each pasta shell with the ricotta filling. Don’t overfill them, just enough to fill the cavity.
  4. Arrange the Shells: Spread a thin layer of the meat sauce on the bottom of the prepared baking dish. Arrange the filled pasta shells on top of the sauce in a single layer. You may need to nestle them close together to fit them all in.
  5. Top with Sauce and Cheese: Pour the remaining meat sauce over the filled shells, making sure to cover them evenly. Sprinkle the shredded mozzarella cheese over the top.

Baking the Casserole:

Almost there! Now it’s time to bake the casserole until it’s bubbly and golden brown. The aroma that will fill your kitchen is simply divine!

  1. Bake: Cover the baking dish with aluminum foil and bake for 20 minutes. Then, remove the foil and bake for another 15-20 minutes, or until the cheese is melted and bubbly and the casserole is heated through. The top should be lightly browned.
  2. Rest: Let the casserole rest for 10-15 minutes before serving. This allows the cheese to set slightly and makes it easier to cut and serve.

Tips and Variations:

Want to customize this recipe to your liking? Here are a few ideas:

  • Add Vegetables: Feel free to add other vegetables to the meat sauce, such as chopped bell peppers, mushrooms, or zucchini.
  • Use Different Cheese: You can substitute the mozzarella cheese with provolone, Monterey Jack, or a blend of Italian cheeses.
  • Spice it Up: Add a pinch of red pepper flakes to the meat sauce for a little bit of heat.
  • Make it Vegetarian: Omit the ground beef and add more vegetables, or use a plant-based ground meat substitute.
  • Add Spinach: Mix some cooked and drained spinach into the ricotta filling for added nutrients and flavor.
  • Use Different Herbs: Experiment with different herbs in the meat sauce, such as thyme, rosemary, or marjoram.
  • Make it Ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Just add a few extra minutes to the baking time.
  • Freeze it: This casserole freezes well. Let it cool completely, then wrap it tightly in plastic wrap and aluminum foil. It can be stored in the freezer for up to 3 months. Thaw it overnight in the refrigerator before baking.

Serving Suggestions:

This Beef Shells Casserole is a complete meal on its own, but here are a few serving suggestions to make it even more special:

  • Serve with a side salad and some crusty bread for dipping in the sauce.
  • Garnish with fresh basil or parsley.
  • Serve with a glass of red wine.
  • Offer a sprinkle of extra Parmesan cheese at the table.

Why This Recipe Works:

This Beef Shells Casserole is a classic comfort food dish that’s sure to please everyone. The combination of savory meat sauce, creamy ricotta filling, and melted mozzarella cheese is simply irresistible.

Troubleshooting:

  • Sauce is too watery: If the sauce is too watery, simmer it uncovered for a longer period of time to allow some of the liquid to evaporate.
  • Cheese is browning

    Cheesy Goodness Overload

    Don’t be shy with the cheese! Experiment with different types of cheese, such as Gruyere, Monterey Jack, or even a smoked Gouda. A blend of cheeses will create a more complex and interesting flavor profile.

    Vegetarian Delight

    For a vegetarian version, substitute the ground beef with lentils or crumbled plant-based meat. You can also add extra vegetables, such as mushrooms, spinach, or kale.

    Make it Ahead

    This casserole is perfect for meal prepping! You can assemble it ahead of time and store it in the refrigerator for up to 24 hours before baking. Just add a few extra minutes to the baking time to ensure it’s heated through.
