How to Make Instant Pot Spaghetti Dinner

Step 1: Sauté Aromatics and Meat

Turn on your Instant Pot’s sauté function and heat olive oil. Add diced onions and garlic, cooking until fragrant and translucent. Add ground beef or sausage and brown thoroughly, breaking it up with a spoon.

Step 2: Add Tomatoes and Seasonings

Stir in crushed tomatoes, tomato paste, Italian seasoning, salt, and pepper. Mix everything well, ensuring the tomato paste is evenly incorporated for a rich sauce.

Step 3: Add Pasta and Liquid

Break spaghetti noodles in half to fit into the pot, layering them evenly over the sauce without stirring. Pour in water or broth until the pasta is just covered. This helps prevent sticking and ensures even cooking.

Step 4: Pressure Cook

Secure the lid and set your Instant Pot to high pressure for 8 minutes. Once cooking finishes, use quick-release to avoid overcooked pasta.

Step 5: Final Stir and Serve

Open the lid carefully, give the spaghetti a good stir to mix sauce and noodles evenly. Adjust seasoning if needed, and it’s ready to plate.

Pro Tips for Making Instant Pot Spaghetti Dinner

• Don’t stir before cooking: Avoid stirring the pasta into the sauce initially to prevent clumping or sticking at the bottom.
• Use the right amount of liquid: Just enough water or broth to cover the pasta ensures even cooking without mushiness.
• Quick release carefully: Using quick release prevents the pasta from overcooking and keeps it perfectly al dente.
• Double up for leftovers: This recipe scales well, making it perfect for batch cooking or meal prep.
• Add fresh herbs at the end: Sprinkle fresh basil or parsley after cooking for a bright, fresh flavor boost.

FAQs

Can I use a different type of pasta?

Absolutely! While spaghetti works best, you can use other long pasta like linguine or fettuccine. Just adjust the cooking time slightly if needed.

Do I need to pre-soak the pasta?

No pre-soaking is required. The pressure cooking process hydrates and cooks the pasta perfectly within the recipe’s set time.

Is this recipe good for gluten-free diets?

Yes! Just replace regular spaghetti with gluten-free pasta, and be mindful of any added ingredients to ensure they’re gluten-free as well.

Can I make this vegan?

Definitely. Omit the meat and use vegetable broth along with your preferred plant-based protein or extra veggies for a delicious vegan version.

What if my Instant Pot doesn’t have a sauté function?

You can brown the meat and sauté aromatics in a separate pan before adding them to the Instant Pot to follow the recipe instructions smoothly.
