What Ingredients You Will Need

This creamy Instant Pot spaghetti recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying, silky texture without the fuss. Most of these are pantry staples, and substitutions are easy if needed.

• Spaghetti pasta (8 ounces / 225 grams, broken in half to fit the pot)
• Olive oil (2 tablespoons, for sautéing)
• Ground beef or Italian sausage (1 pound / 450 grams, optional for a meatier meal)
• Yellow onion (1 medium, finely chopped)
• Garlic cloves (3 large, minced)
• Crushed tomatoes (1 can, 28 ounces / 800 grams, use San Marzano for best flavor)
• Tomato sauce (1 can, 8 ounces / 225 grams, adds depth to the sauce)
• Chicken or vegetable broth (3 cups / 720 ml, low sodium preferred)
• Cottage cheese (1 cup / 225 grams, small-curd for creaminess)
• Parmesan cheese (½ cup / 50 grams, freshly grated)
• Italian seasoning (1 teaspoon, a blend of oregano, basil, thyme)
• Red pepper flakes (¼ teaspoon, optional for a subtle kick)
• Salt and black pepper (to taste)
• Fresh basil or parsley (for garnish, optional)

If you’re dairy-free, swap cottage cheese with a creamy dairy-free yogurt or vegan cream cheese. For gluten-free, use gluten-free spaghetti—just check the cooking time as it may vary slightly. Also, frozen spinach or mushrooms make great mix-ins if you want to sneak in some veggies. I tend to stick with the classic combo, but you can get creative!

Equipment Needed

• Instant Pot or any electric pressure cooker: This is the star of the show. If you don’t own one, a heavy-bottomed pot with a lid can work, but you’ll lose the speed and convenience.
• Wooden spoon or silicone spatula: For sautéing and stirring without scratching your pot.
• Measuring cups and spoons: Precision matters here to get that perfect sauce consistency.
• Colander: Optional, if you want to rinse pasta (I usually don’t).

If your Instant Pot has a sauté function, you’re golden. For budget-friendly options, brands like Instant Pot Duo are reliable and versatile. I like to keep my pot clean with a soft sponge and avoid abrasive cleaners to keep that non-stick surface happy.

Preparation Method

1. Sauté the aromatics and meat (10 minutes): Set your Instant Pot to sauté mode and heat the olive oil. Add chopped onion and garlic, stirring for about 3 minutes until softened and fragrant. If using ground beef or sausage, add it now, breaking it up with your spoon until browned and cooked through (about 7 minutes). Drain excess fat if necessary.
2. Add the tomatoes and seasoning (2 minutes): Pour in the crushed tomatoes and tomato sauce. Stir in Italian seasoning, red pepper flakes, salt, and pepper. Mix well to combine.
3. Layer the spaghetti (no stirring yet, 1 minute): Break the spaghetti in half and layer it evenly over the sauce. Do not stir to prevent sticking. Pour the broth gently over the pasta to cover it as much as possible.
4. Pressure cook (8 minutes): Seal the Instant Pot lid and set it to manual high pressure for 8 minutes. It will take a few minutes to come up to pressure.
5. Quick release and stir (5 minutes): When cooking is done, carefully quick release the pressure. Open the lid and stir the pasta gently. It might look a bit saucy but don’t worry.
6. Add cottage cheese and Parmesan (3 minutes): Stir in the cottage cheese and Parmesan until the sauce becomes creamy and coats the spaghetti beautifully.
7. Final taste and garnish: Taste and adjust salt or pepper if needed. Sprinkle fresh basil or parsley before serving for a fresh pop of color and flavor.

Note: If the sauce seems too thick, add a splash of broth or water to loosen it. The pasta will continue to absorb the sauce as it sits, so it’s best enjoyed right away or stored properly.

Cooking Tips & Techniques

Here are some nuggets from my kitchen experience that make this creamy Instant Pot spaghetti shine every time:

• Don’t stir the pasta before cooking: Trust me, it’s tempting, but stirring causes clumps and sticking. Layer the pasta and pour broth on top gently instead.
• Use small-curd cottage cheese: Larger curds can give a lumpy sauce. Small-curd blends right in for that silky texture.
• Quick release carefully: The pot is hot and the sauce steamy. Use a long utensil and keep your face away to avoid burns.
• Brown your meat well: This step adds depth to the sauce flavor. Don’t rush it—let the meat get a nice crust.
• Adjust seasoning last: The cheese adds saltiness, so taste after mixing in the dairy to avoid over-salting.
• Multitask while it cooks: Use the pressure cooking time to chop salad or set the table. Instant Pot dinners are lifesavers for busy nights.

Variations & Adaptations

Want to switch things up? Here are some tasty twists that I’ve tried and loved:

• Vegetarian Version: Skip the meat and add extra mushrooms or zucchini for a veggie-packed meal.
• Spicy Kick: Add a diced jalapeño or extra red pepper flakes for more heat.
• Cheesy Upgrade: Stir in shredded mozzarella or a dollop of cream cheese with the cottage cheese for an ultra-rich sauce.
• Gluten-Free: Use gluten-free spaghetti and check cooking times, as some cook faster.
• Seasonal Freshness: In summer, toss in fresh cherry tomatoes and basil instead of canned tomatoes for a bright flavor.

Personally, adding a handful of fresh spinach right after cooking is my quick way to sneak in greens without messing with the creamy texture.

Serving & Storage Suggestions

This creamy Instant Pot spaghetti is best served hot, garnished with fresh herbs and a sprinkle of Parmesan. It pairs beautifully with a crisp green salad or garlic bread to mop up every bit of that luscious sauce. For drinks, a chilled glass of white wine or sparkling water with lemon brightens the meal nicely.

Leftovers keep well in an airtight container in the fridge for 3-4 days. Reheat gently on the stove or in the microwave with a splash of broth or water to loosen the sauce. You can also freeze portions for up to 2 months, though the texture may soften slightly.

Interestingly, the flavors actually deepen after a day as the sauce and pasta soak up all those herby, cheesy notes. So, if you’re not in a rush, make it ahead and enjoy the next-day magic!

Nutritional Information & Benefits

This creamy Instant Pot spaghetti meal packs a decent nutritional profile thanks to its balanced ingredients. Estimated per serving (serves 4): approximately 450 calories, 25g protein, 50g carbohydrates, and 15g fat.
