One-Pot Cheesy Beef and Shells

Step 2: Sauté Aromatics

Add the chopped onion and cook for 3–4 minutes until softened. Then stir in the minced garlic, Italian seasoning, red pepper flakes, salt, and black pepper. Cook for another 1–2 minutes until fragrant.


Step 3: Build the Sauce

Mix in the tomato paste and cook for 1 minute to deepen its flavor. Add the diced tomatoes (with juice) and the broth. Stir well to combine. Bring the mixture to a gentle boil.


Step 4: Cook the Pasta

Add the uncooked pasta shells directly into the pot. Reduce the heat to medium-low, cover, and simmer for 12–15 minutes, stirring occasionally to prevent sticking. Cook until the pasta is tender and has absorbed most of the liquid.

Tip: Keep an eye on the liquid. If it evaporates too quickly, add a splash of water or broth to prevent burning.


Step 5: Make It Cheesy

Once the pasta is tender, stir in the heavy cream or milk. Gradually add the shredded mozzarella and Parmesan cheese, stirring until the cheese melts and forms a creamy sauce that clings to the pasta and beef.


Step 6: Final Touches

Taste and adjust seasoning with additional salt and pepper if needed. Sprinkle chopped fresh parsley on top for a pop of color and freshness.


Serving Suggestions:

Serve this dish hot, straight from the pot. Pair it with a simple side salad or garlic bread for a full meal. It also reheats beautifully, making it ideal for leftovers.


Tips for Success:

  1. Cheese Variety: Experiment with cheddar, provolone, or a mix for a richer flavor.
  2. Vegetable Boost: Add chopped bell peppers, zucchini, or spinach for extra nutrients.
  3. Make Ahead: You can prepare the sauce and beef ahead of time, then just cook the pasta and combine when ready.
