Ingredients

For the Meatballs:

1 lb Lean Ground Beef (80/20)
1/2 cup Panko Breadcrumbs
1/4 cup Grated Parmesan Cheese
1 Egg, lightly beaten
2 cloves Garlic, minced
1 teaspoon Dried Italian Seasoning
1/2 teaspoon Salt
1/4 teaspoon Black Pepper

For the Spaghetti:

1 tablespoon Olive Oil
1 Yellow Onion, chopped
1 (24 oz) jar Marinara Sauce
3 cups Beef or Chicken Broth
8 oz Spaghetti Noodles, broken in half
For Garnish: Fresh basil, extra Parmesan cheese

Step-by-Step Instructions

Make the Meatballs: In a large bowl, gently combine the ground beef, panko breadcrumbs, Parmesan cheese, egg, minced garlic, Italian seasoning, salt, and pepper. Be careful not to overmix. Roll the mixture into 1.5-inch meatballs.

Sauté Meatballs: Set your Instant Pot to the “Sauté” function on high. Add the olive oil. Once hot, carefully place the meatballs in the pot in a single layer (work in batches if needed) and brown them on all sides. Remove the meatballs and set them aside.
Sauté Aromatics: Add the chopped onion to the pot and cook for 3-4 minutes until softened. Add a splash of broth and use a wooden spoon to scrape up any browned bits from the bottom of the pot. Turn off the Sauté function.
Layer the Ingredients: Pour the remaining broth into the pot. Take the spaghetti noodles, broken in half, and arrange them in the pot in a crisscross pattern to prevent clumping. Do not stir.

Add Sauce and Meatballs: Pour the entire jar of marinara sauce over the spaghetti, spreading it to cover the noodles as much as possible. Do not stir. Gently place the browned meatballs on top of the sauce.
Pressure Cook: Secure the lid and set the steam release valve to the “Sealing” position. Select “Pressure Cook” (or “Manual”) and cook on high pressure for 8 minutes.
Release and Serve: Once the cooking time is complete, perform a quick release by carefully moving the valve to the “Venting” position. Once the pin has dropped, open the lid. Stir everything together gently. The sauce will thicken as it sits. Serve hot, garnished with fresh basil and extra Parmesan cheese.

Tips & Variations

Pro Tip: Layering the ingredients in the correct order (liquid on the bottom, pasta, then sauce on top) is the most important step to prevent the dreaded “Burn” notice on your Instant Pot.
Shortcut: For a super-fast meal, you can use a bag of pre-cooked, frozen meatballs. Skip the searing step and add them on top of the sauce.
Make it Spicy: Add 1/2 teaspoon of red pepper flakes with the onions for a spicy arrabbiata-style sauce.

Add Veggies: Sauté some chopped bell peppers or mushrooms along with the onion for extra nutrition.

Frequently Asked Questions (FAQ)

Do I have to break the spaghetti?
- Yes, breaking the spaghetti in half is necessary for it to fit and cook properly below the liquid level in the Instant Pot.

How do I store and reheat leftovers?
- Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave with a splash of water to loosen the sauce.
Can I use other pasta shapes?
- Yes, other shapes like penne, rotini, or bow ties work well. You may need to adjust the cooking time slightly (a good rule of thumb is to take the package cooking time, divide by two, and subtract one minute).

Serving Suggestions

This Instant Pot Spaghetti and Meatballs is a fantastic one-pot meal on its own. It’s best served hot right from the pot with a generous sprinkle of freshly grated Parmesan cheese and some torn fresh basil leaves. A side of garlic bread and a simple green salad complete the classic Italian-American experience.
