Essential Ingredients Guide
- Pasta shells: Choose medium size for ideal sauce-to-pasta ratio. Quality brands hold shape better.
- Ground beef: Select 80/20 for best flavor and moisture. Avoid extra lean which can become dry.
- Cream of mushroom soup: Creates rich base. Premium brands offer better mushroom pieces.
- Sour cream: Full-fat provides best texture. Room temperature prevents curdling.
- Cheddar cheese: Sharp variety adds robust flavor. Freshly grated melts more smoothly.
- Mozzarella: Whole milk type ensures proper melting and stretchy texture.
- Onion: Yellow or white varieties work well. Dice finely for even distribution.
- Garlic: Fresh cloves provide best flavor. Mince just before using.
- Seasonings: Fresh or recently purchased dried herbs ensure maximum flavor.
Creating Your Casserole
- Preparation Method:
- Position oven rack in center and preheat to 375°F. This temperature ensures even cooking and proper cheese melting. Choose a deep 9x13 baking dish, coating thoroughly with cooking spray, including corners and sides. Gather all ingredients measured and ready, including pre-shredded cheese and chopped herbs.
- Cooking Technique:
- Fill large pot with 4 quarts water. Add 1 tablespoon salt - water should taste like sea water. Bring to vigorous boil before adding pasta. Cook shells just until al dente, about 2 minutes less than package directions. Test by biting - pasta should have slight resistance. Drain thoroughly but don't rinse to preserve starch that helps sauce adhere.
- Browning Process:
- Heat large, heavy-bottomed skillet over medium-high heat until drop of water sizzles. Add ground beef and diced onion together, breaking meat into small, uniform pieces with wooden spoon. Cook until beef develops brown crust and onions become translucent, about 7-8 minutes. Add minced garlic in final minute. Drain fat while keeping flavorful browned bits in pan.
- Building Flavors:
- Return skillet to medium heat. Add diced tomatoes with their juice first to deglaze pan, scraping up browned bits. Pour in mushroom soup and beef broth, stirring until smooth. Incorporate room temperature sour cream gradually while stirring constantly. Season with Italian herbs, paprika, salt, and pepper. Simmer 5-7 minutes until slightly thickened, stirring occasionally to prevent sticking.
- Layering Technique:
- Fold cooked pasta into sauce mixture gently but thoroughly, ensuring each shell is well-coated. Transfer to prepared baking dish, spreading evenly to corners. Top with combined cheddar and mozzarella, creating complete coverage. Slight peaks and valleys in cheese layer develop appealing texture when melted.
