Step-by-step instructions
Follow these detailed steps to achieve perfectly layered, cheesy pasta results consistently.
Step 1: Brown the meat
Heat olive oil in a large skillet over medium-high heat until shimmering hot. Add ground beef and cook thoroughly, breaking apart with a spatula until no pink remains visible anywhere.
Step 2: Add vegetables and simmer
Stir diced red and green bell peppers directly into the browned meat mixture. Cook for five minutes until peppers soften slightly but retain their bright, vibrant color and crisp texture.
Step 3: Prepare the pasta base
Boil rotini pasta according to package directions until al dente texture is achieved perfectly. Drain well and transfer immediately to a greased nine-by-thirteen inch baking dish for assembly.

Step 4: Create creamy layer
Pour heavy cream evenly over the cooked pasta in the prepared baking dish. Stir gently to coat each spiral noodle completely with the rich, luxurious cream before adding other components.
Step 5: Layer the meat sauce
Spoon the seasoned beef and pepper mixture uniformly over the creamy pasta base. Spread carefully to ensure even distribution across the entire surface area of the baking dish.
Step 6: Add tomato sauce
Ladle marinara sauce generously over the meat layer, covering all exposed areas completely. This adds moisture and tangy flavor that balances the richness of cream and cheese effectively.
Step 7: Top with cheese
Sprinkle shredded mozzarella cheese evenly across the entire top surface of the casserole. Ensure complete coverage so every serving gets that signature golden, bubbly cheese crust when baked.
