Looking for a quick and satisfying dinner that mimics the flavors of classic baked spaghetti? This Instant Pot baked spaghetti recipe delivers a cheesy, hearty dish with minimal effort and time. Perfect for busy weeknights or when you crave comfort food without the long oven bake.
Ingredients
- 12 oz (340 g) spaghetti or other long pasta
- 1 lb (450 g) ground beef or Italian sausage
- 1 small onion, diced
- 3 cloves garlic, minced
- 24 oz (700 g) marinara or tomato sauce
- 2 cups (475 ml) water or beef broth
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried oregano or Italian seasoning
- 1 cup (100 g) shredded mozzarella cheese
- 1/2 cup (50 g) grated Parmesan cheese
- Optional: fresh basil or parsley for garnish
Instructions
- Set the Instant Pot to sauté mode. Add the ground beef or sausage along with diced onion. Cook, stirring occasionally, until browned and onions are translucent, about 5-7 minutes. Drain excess fat if necessary.
- Add minced garlic, salt, pepper, and Italian seasoning to the meat. Cook for another minute until fragrant.
- Pour in the marinara sauce and stir to combine. Let it simmer for 2 minutes to marry the flavors.
- Break the spaghetti in half and add it to the pot, pressing down gently to submerge the noodles in the sauce. Pour water or broth over the top, ensuring the noodles are mostly covered but not submerged completely.
- Close the lid of the Instant Pot, set the valve to sealing, and cook on high pressure for 8 minutes.
- Once cooking is complete, perform a quick release by carefully turning the valve to venting. Open the lid once the pressure subsides.
- Stir the pasta gently to distribute the sauce evenly. Sprinkle mozzarella and Parmesan cheeses on top.
- Close the lid again and let the residual heat melt the cheese for 2-3 minutes. Alternatively, you can use the sauté mode briefly to melt the cheese thoroughly.
- Garnish with chopped fresh basil or parsley if desired. Serve hot directly from the pot or transfer to a serving dish.
Tips
- For a vegetarian version, substitute the meat with sautéed vegetables like zucchini, mushrooms, or eggplant, and use plant-based cheese.
- If you prefer a creamier texture, stir in a splash of heavy cream or a dollop of ricotta cheese after cooking.
- To prevent sticking, ensure the noodles are fully submerged in the liquid before cooking. Adjust water quantity if needed.
- Leftovers can be refrigerated in an airtight container for up to 3 days. Reheat in the microwave or on the stovetop, adding a splash of water or broth to loosen the sauce.
Serving Suggestions
Serve this baked spaghetti with a crisp green salad and garlic bread for a complete meal. A side of roasted vegetables or a simple Caesar salad pairs beautifully with the rich, cheesy pasta.
Variations
Try adding cooked spinach, sautéed bell peppers, or mushrooms to the sauce for extra flavor and nutrition. For a spicy kick, include red pepper flakes or hot Italian sausage. You can also top with extra cheese or breadcrumbs before sealing the dish for a crunchy topping.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave in 30-second intervals, stirring in between, until heated through. Alternatively, reheat on the stovetop over low heat, adding a splash of water or broth to restore moisture. For best results, consume within 2-3 days for freshness and safety.
Frequently Asked Questions
Can I use gluten-free pasta in this recipe?
Yes, gluten-free spaghetti or other pasta can be used. Keep in mind that cooking times may vary slightly, so check the pasta for doneness after cooking and adjust accordingly.
Can I make this dish vegan?
Absolutely. Use plant-based ground meat or lentils, vegan marinara, and dairy-free cheese options. Also, substitute the cheese toppings with vegan cheese or nutritional yeast for added flavor.
What if my noodles are not fully cooked after pressure cooking?
If the noodles are undercooked, simply close the lid and cook on high pressure for an additional 1-2 minutes. Be cautious of overcooking, which can make the pasta mushy.
Can I prepare this dish in advance?
Yes, you can assemble all ingredients (except cheese) in the Instant Pot and keep refrigerated for up to 24 hours before cooking. Add the cheese after pressure cooking and melting it before serving.
Is it necessary to break the spaghetti in half?
Breaking the noodles helps them fit better in the Instant Pot and ensures even cooking. However, if you prefer longer spaghetti, you can try to fit them in unbroken, but cooking time may need adjustment.
Can I use different types of cheese?
Yes, feel free to experiment with cheeses like provolone, cheddar, or gouda for varied flavors. Just keep in mind that cheese melting behavior may vary depending on the type used.
