Ingredients for the Perfect Instant Pot Spaghetti

To create this culinary masterpiece in your pressure cooker, you’ll need these simple and readily available ingredients. Don’t worry, no fancy grocery store runs required!

• 1 pound ground beef or Italian sausage: You can use lean ground beef, ground turkey, or Italian sausage (sweet or hot, depending on your preference). For a vegetarian option, you can substitute with crumbled plant-based ground meat or even lentils for a heartier texture.
• 1 medium onion, chopped: Yellow or white onion works perfectly. Diced finely for even cooking.
• 2 cloves garlic, minced: Freshly minced garlic is always best for flavor. You can also use pre-minced garlic from a jar for convenience.
• 1 (28 ounce) can crushed tomatoes: Good quality crushed tomatoes form the base of your delicious sauce. Look for fire-roasted crushed tomatoes for a deeper flavor.
• 1 (15 ounce) can tomato sauce: Tomato sauce adds body and richness to the sauce.
• 1 (15 ounce) can diced tomatoes, undrained: Diced tomatoes provide texture and a slightly brighter flavor.
• 1 cup beef broth or chicken broth: Broth adds moisture and flavor. Beef broth enhances the beef flavor, while chicken broth offers a slightly lighter taste. Vegetable broth is a great option for vegetarians.
• 1 teaspoon dried oregano: Oregano is a classic Italian herb that adds warmth and depth to the sauce.
• 1 teaspoon dried basil: Basil complements oregano and adds a sweet, aromatic note.
• ½ teaspoon dried thyme: Thyme adds a subtle earthy flavor that rounds out the herb blend.
• ½ teaspoon salt: Adjust to taste. Remember that broth can be salty, so start with less and add more if needed.
• ¼ teaspoon black pepper: Freshly ground black pepper is preferred for the best flavor.
• 1 pound spaghetti: Regular spaghetti works best. You can also use other long pasta shapes like linguine or fettuccine, but cooking times might need slight adjustments. Whole wheat spaghetti can also be used, but may require a minute or two extra cooking time.
• 2 tablespoons olive oil: Used for sautéing the meat and vegetables.
• Optional: 1 red bell pepper, diced: Adds sweetness and color to the sauce.
• Optional: ½ cup grated Parmesan cheese, for serving: For topping and extra flavor.
• Optional: Fresh parsley, chopped, for garnish: Adds freshness and visual appeal.
• Optional: Pinch of red pepper flakes: For a touch of heat.
• Optional: 1 tablespoon sugar: To balance the acidity of the tomatoes, especially if using lower quality canned tomatoes.

Step-by-Step Instructions for Instant Pot Spaghetti Perfection

Follow these easy instructions to create mouthwatering Instant Pot Spaghetti in minutes. It’s so simple, even beginner cooks can nail it!

1. Sauté the Aromatics and Brown the Meat: Turn your Instant Pot to the “Sauté” function on “Normal” or “More” setting. Add olive oil to the pot. Once the oil is heated, add the chopped onion and diced bell pepper (if using). Sauté for 3-4 minutes, until the onion is softened and translucent. Add the minced garlic and sauté for another minute until fragrant, being careful not to burn the garlic.
2. Brown the Ground Meat: Add the ground beef or Italian sausage to the pot. Break it up with a spoon and cook until browned, draining off any excess grease if necessary. If using Italian sausage, you can remove the casings for easier browning.
3. Add the Sauce Ingredients: Turn off the “Sauté” function. Pour in the crushed tomatoes, tomato sauce, diced tomatoes (undrained), beef broth (or chicken or vegetable broth), dried oregano, dried basil, dried thyme, salt, and black pepper. If you like a touch of heat, add a pinch of red pepper flakes at this point. If your tomatoes are particularly acidic, you can add a tablespoon of sugar to balance the flavors.
4. Break and Layer the Spaghetti: Break the spaghetti noodles in half (or thirds if you prefer shorter noodles) and place them in the Instant Pot in a crisscross pattern, ensuring they are mostly submerged in the liquid. Do not stir at this point. This layering technique helps prevent the noodles from sticking together and ensures even cooking. Push the noodles down gently with a spoon to ensure they are covered by the liquid.
5. Pressure Cook: Secure the Instant Pot lid and set the valve to “Sealing.” Select “Manual” or “Pressure Cook” and set the cooking time for 8 minutes at high pressure.
6. Release Pressure: Once the cooking cycle is complete, let the pressure release naturally for 5 minutes. After 5 minutes of natural pressure release, do a quick pressure release by carefully moving the valve to the “Venting” position to release any remaining pressure. Be cautious of the steam when performing a quick release.
7. Stir and Serve: Once all pressure is released and the float valve has dropped, carefully remove the lid. Stir the spaghetti and sauce thoroughly to combine everything. The sauce will thicken as you stir. If the sauce is too thick for your liking, you can add a splash of extra broth or water to reach your desired consistency. Taste and adjust seasonings if needed, adding more salt, pepper, or herbs to your preference.
8. Serve Immediately: Serve hot, garnished with grated Parmesan cheese and fresh parsley, if desired. Enjoy your incredibly easy and delicious Instant Pot Spaghetti!

Additional Tips for Perfect Instant Pot Spaghetti

Follow these tips to ensure your Instant Pot Spaghetti is a resounding success every time:

1. Don’t Overcook the Pasta: 8 minutes at high pressure followed by a 5-minute natural release is generally perfect for spaghetti. Overcooking will result in mushy noodles. If you prefer a slightly firmer pasta, you can reduce the cooking time by 1 minute.
2. Layer the Ingredients Correctly: Layering the spaghetti noodles on top of the sauce ingredients and ensuring they are mostly submerged is crucial for even cooking and preventing sticking. Avoid stirring before pressure cooking.
3. Use Enough Liquid: The broth is essential for creating steam and pressure in the Instant Pot and for cooking the pasta. Make sure there is enough liquid to cover most of the noodles. If needed, add a little extra broth or water.
4. Don’t Overfill the Instant Pot: Do not fill the Instant Pot beyond the maximum fill line. For this recipe, using a 6-quart or larger Instant Pot is recommended, especially if making a larger batch.
5. Adjust Seasoning to Taste: Taste the sauce after cooking and adjust seasonings as needed. You may want to add more salt, pepper, herbs, or even a pinch of sugar to balance the flavors to your liking.

Frequently Asked Questions (FAQ) About Instant Pot Spaghetti

Here are some common questions people have about making Instant Pot Spaghetti:

Q1: Can I use frozen ground beef?
A: Yes, you can use frozen ground beef, but you will need to sauté it for a bit longer until it’s browned. You may need to break it apart as it thaws during the sauté process. Ensure it’s fully browned before adding the other sauce ingredients.

Q2: Can I use different types of pasta?
A: Yes, you can use other long pasta shapes like linguine, fettuccine, or even angel hair. However, cooking times may need slight adjustments. For thicker pastas like fettuccine, you might need to add a minute or two to the cooking time. For thinner pastas like angel hair, you might need to reduce the cooking time by a minute. Always check the pasta package for recommended cooking times and adjust accordingly.

Q3: How do I prevent the pasta from sticking together?
A: Breaking the spaghetti noodles in half and layering them in a crisscross pattern helps prevent sticking. Also, ensuring the noodles are mostly submerged in liquid before pressure cooking is important. Avoid stirring before pressure cooking. Stir thoroughly immediately after pressure cooking and releasing pressure to separate any noodles that might be slightly stuck.

Q4: Can I add vegetables to the sauce?
A: Absolutely! Adding vegetables is a great way to boost the nutritional value and flavor of your Instant Pot Spaghetti. Diced bell peppers, zucchini, mushrooms, spinach, or carrots can be added during the sauté step or along with the sauce ingredients. Heartier vegetables like carrots and potatoes might need to be sautéed a bit longer to soften before pressure cooking.

Q5: Can I make this recipe ahead of time?
A: Instant Pot Spaghetti is best served fresh, but you can definitely make it ahead of time. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. When reheating, you may need to add a splash of water or broth as the pasta tends to absorb the sauce as it sits. Reheat gently in the microwave or on the stovetop until heated through.

Instant Pot Spaghetti is truly a weeknight dinner hero. It’s quick, easy, delicious, and a guaranteed family favorite. So, ditch the multiple pots and pans and embrace the simplicity and flavor of this incredible one-pot meal. Happy cooking!
