Ingredient Overview: What You’ll Need
Hot Italian Sausage
Adds rich flavor, a touch of heat, and lots of umami. Use bulk sausage or remove the casing from links. Pork sausage is classic, but chicken or turkey sausage works too.
Pasta (Penne or Rigatoni)
Short pasta with ridges holds the sauce well. Penne is ideal for catching bits of sausage and sauce.
Onion & Garlic
Foundational aromatics. Sautéed onions provide sweetness and depth; garlic boosts flavor and ties it to Italian roots.
Crushed Tomatoes or Tomato Passata
Forms the base of the sauce. Use high-quality canned tomatoes with no added sugar or herbs for better control over flavor.
Red Pepper Flakes
Intensifies the sausage’s heat. Add more or less depending on your preference.
Spinach
Adds freshness and nutrients. Wilts beautifully into the sauce and balances the richness.
Olive Oil, Salt & Pepper
Simple ingredients, essential for sautéing and seasoning.
Fresh Parsley (Optional)
A finishing touch for color and freshness.
