- Ground beef: 85% lean works well, providing flavor without excess grease.
- Olive oil: Used for sautéing, it adds a subtle richness to the dish.
- Onion and garlic: These aromatics form the flavor base of the sauce.
- Marinara sauce and diced tomatoes: Select a quality marinara sauce and canned diced tomatoes for convenience and consistent results.
- Italian seasoning, salt, and pepper: These seasonings enhance the overall flavor of the dish.

Professional Tips & Techniques
- Sautéing: Always start by sautéing the ground beef and aromatics to develop deep flavors before adding the sauce and pasta.
- Layering: Layer the broken spaghetti on top of the sauce without stirring. This prevents the pasta from sticking together during cooking.
- Cooking time: The 8-minute high-pressure cook time is optimal for al dente spaghetti. Adjust by a minute or two if you prefer softer pasta.
- Pressure release: A 5-minute natural pressure release followed by a quick release ensures the pasta is cooked perfectly without becoming mushy.
- Sauce consistency: If the sauce is too thin after cooking, let it simmer on sauté mode for a few minutes to thicken. The starch from the pasta will help thicken the sauce naturally.
Recipe Variations
- Vegetarian: Omit the ground beef and add extra vegetables like bell peppers, zucchini, or mushrooms for a meatless version.
- Spicy: Add red pepper flakes or diced jalapeños to the sauce for a kick of heat.
- Meat lover’s: Include Italian sausage or pepperoni along with the ground beef for a heartier dish.
- Seafood: Substitute the ground beef with shrimp or clams for a seafood twist on the classic.
- Gluten-free: Use gluten-free spaghetti and ensure your marinara sauce is gluten-free.
- Low-carb: Replace traditional pasta with zucchini noodles or spaghetti squash for a lower-carb option.
- Cheesy: Stir in shredded mozzarella or ricotta cheese after cooking for a creamy, cheesy variation.
- Herbaceous: Add fresh herbs like parsley, oregano, or thyme to the sauce for an extra burst of flavor.
Serving Suggestions
- Classic Italian: Serve with a side of garlic bread and a simple green salad dressed with olive oil and balsamic vinegar.
- Family-style: Present the spaghetti in a large serving dish, allowing everyone to help themselves. Add meatballs or Italian sausage on the side for variety.
- Elegant dinner: Plate individual portions, garnished with fresh basil leaves and a drizzle of extra virgin olive oil for a more sophisticated presentation.
- Kid-friendly: Serve with a sprinkle of Parmesan cheese and a side of steamed vegetables or fruit to balance the meal.
- Picnic or potluck: Transport the spaghetti in a slow cooker set to warm, keeping it ready to serve at your next gathering.
