Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Cook 12 jumbo pasta shells in a large pot of salted boiling water for 8-10 minutes until al dente; drain and set aside. Heat 2 tbsp olive oil in a skillet over medium heat, add 1/2 cup finely chopped onion and 2 minced garlic cloves, and cook for 3 minutes until softened and fragrant.
  2. Step 2: Add 1 lb ground beef to skillet, breaking it up with a spoon, and cook until browned (5-7 minutes). Stir in 1/2 cup tomato sauce and 1/4 cup chopped fresh basil, then simmer for 5 minutes. Remove from heat and let cool slightly.
  3. Step 3: In a bowl, mix 1/2 cup ricotta cheese, 1/2 cup shredded mozzarella, 1/4 cup grated parmesan, and 1/4 cup milk; season with salt and pepper to taste. Spoon filling into cooked pasta shells, arrange in a baking dish, pour remaining sauce over shells, cover with foil, and bake for 25 minutes until bubbly and golden.
