What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and the creamy Parmesan sauce comes together with just a few additions.

• Spaghetti pasta: 8 ounces (225 grams), broken in half to fit the pot better (I prefer Barilla for consistent texture).
• Chicken broth: 3 cups (720 ml), for cooking the pasta and infusing flavor (you can use vegetable broth for a vegetarian option).
• Heavy cream: 1 cup (240 ml), adds richness and creaminess to the sauce (substitute with half-and-half for lighter version).
• Parmesan cheese: 1 cup (100 grams), freshly grated for the best flavor and melt (avoid pre-grated if you can—it really makes a difference).
• Garlic: 3 cloves, minced, to add aromatic depth.
• Butter: 2 tablespoons (28 grams), unsalted and softened, for a silky mouthfeel.
• Salt: 1 teaspoon, plus more to taste.
• Black pepper: ½ teaspoon freshly ground, for a gentle kick.
• Fresh parsley: 2 tablespoons, chopped, optional for garnish and a pop of green.

Substitution tips: Use gluten-free pasta if needed, and swap heavy cream for coconut cream for a dairy-free twist. For a vegan adaptation, plant-based Parmesan alternatives work well, but the flavor will be slightly different.

Equipment Needed

• Instant Pot or electric pressure cooker: A must-have for this recipe. Any 6-quart or larger model works perfectly.
• Measuring cups and spoons: For precise ingredient amounts.
• Wooden spoon or silicone spatula: To stir and scrape the bottom without scratching your pot.
• Cheese grater: Freshly grating Parmesan is worth the minimal effort.
• Colander: Optional, if you prefer to drain the pasta (though this recipe cooks pasta directly in the broth).

If you don’t have an Instant Pot, a similar electric pressure cooker will do, but cooking times may vary slightly. For grating, a microplane works wonders and is easy to clean. Budget-friendly kitchen scales can help with more accurate measurements, especially if you like to bake or cook often.

Preparation Method

1. Prepare the ingredients: Break the spaghetti in half so it fits neatly into your Instant Pot. Mince the garlic and grate the Parmesan cheese. This prep takes about 5 minutes.
2. Sauté the garlic: Set your Instant Pot to sauté mode. Add the butter and let it melt gently (about 1-2 minutes). Toss in the minced garlic and sauté until fragrant but not browned—about 30 seconds to 1 minute. Keep an eye on it to avoid burning.
3. Add broth and pasta: Pour in the chicken broth, stirring to deglaze any browned bits from the bottom (this helps prevent the dreaded burn warning). Add the broken spaghetti in a circular pattern, pushing it down gently to submerge but don’t stir. Cooking time depends on your pasta brand, but 6 minutes at high pressure usually works well.
4. Pressure cook: Seal the Instant Pot lid and set to manual high pressure for 6 minutes. It will take a few minutes to come to pressure before the countdown starts.
5. Quick release: As soon as cooking finishes, perform a quick pressure release to avoid overcooking the pasta. Carefully open the lid once the pin drops.
6. Add cream and cheese: Stir in the heavy cream and gradually add the grated Parmesan cheese, stirring gently to melt and combine. The sauce should thicken slightly and coat the spaghetti beautifully. Add salt and pepper to taste.
7. Final touches: Let the dish rest on warm sauté mode for 2-3 minutes to meld flavors. If the sauce seems too thick, add a splash more broth or cream. Garnish with chopped parsley before serving.

Tip: If your Instant Pot gives a burn warning, it usually means the bottom has bits stuck or not enough liquid. Always deglaze well after sautéing garlic or butter. Also, don’t stir pasta after adding to broth before cooking, or it might clump.

Cooking Tips & Techniques

One trick I learned is to break the spaghetti in half so it fits better and cooks evenly in the Instant Pot. Also, sautéing garlic in butter first gives the sauce a rich base flavor that you can’t get by tossing raw garlic in. Trust me on this one.

Instant Pot cooking can be a bit intimidating at first, but timing here is crucial—6 minutes is perfect for al dente pasta. Overcooking makes it mushy, and undercooking leaves it stiff. Don’t skip the quick release either; it stops the cooking immediately.

For consistency, always use fresh Parmesan. Pre-grated versions often contain additives that prevent melting smoothly. If your sauce looks a bit thin, let it sit on warm sauté mode for a few minutes or add a bit more cheese. I’ve had moments where I rushed to serve, and the sauce was runny—patience pays off!

Multitasking works well here—you can prep your salad or garlic bread while the pasta cooks. Just keep an eye on the Instant Pot to avoid any burn warnings, and always deglaze after sautéing.

Variations & Adaptations

• Vegetarian version: Use vegetable broth instead of chicken broth and add sautéed mushrooms or spinach for extra flavor and nutrition.
• Spicy twist: Add red pepper flakes during the garlic sauté step for a gentle heat that wakes up the creamy sauce.
• Low-carb option: Swap spaghetti for spiralized zucchini or shirataki noodles, but cook separately and toss with the creamy sauce after.
• Dairy-free adaptation: Use coconut cream instead of heavy cream and nutritional yeast in place of Parmesan for a cheesy flavor.
• Protein boost: Stir in cooked shredded chicken or Italian sausage during the final mixing step for a heartier meal.

I personally love adding a handful of fresh basil leaves right before serving—gives it a fresh, herbaceous note that brightens the dish. Feel free to experiment with herbs or add-ins to make this recipe your own.

Serving & Storage Suggestions

This creamy spaghetti is best served hot and fresh from the pot, ideally with a sprinkle of fresh parsley or basil for color and brightness. Pair it with a crisp green salad or some garlic bread to round out the meal nicely. For drinks, a chilled glass of white wine or sparkling water with lemon complements the richness perfectly.

Leftovers store well in an airtight container in the fridge for up to 3 days. When reheating, add a splash of milk or broth to loosen the sauce and warm gently on the stove or in the microwave to avoid drying out. You’ll notice the flavors deepen overnight, making it even better the next day.

If you want to freeze leftovers, portion into freezer-safe containers and thaw in the fridge overnight before reheating. The texture might soften a bit, but it’s still delicious and convenient for busy days.
