Instant Pot Pumpkin Pasta Bake: Creamy Fall Dinner

Ingredients
Main Ingredients
- 12 oz penne pasta
- 1 cup pumpkin puree
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 cup heavy cream
- 2 cups low‑sodium chicken broth
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tsp dried sage
- 1 tbsp olive oil
Seasonings & Flavors
- 1/2 tsp ground nutmeg
- 1/4 tsp red pepper flakes
Optional
- 1/2 cup breadcrumbs
- Extra grated Parmesan
- Chopped fresh parsley
Instructions
- 1Prep Pasta: Add pasta, broth, olive oil, salt, and pepper to the Instant Pot. Stir to coat. Set to high pressure for 4 minutes; quick‑release to avoid overcooking.
- 2Make Pumpkin Sauce: Switch to sauté mode. Stir in pumpkin puree, heavy cream, sage, nutmeg, and red pepper flakes. Simmer 5 minutes until thick, scraping the bottom to prevent scorching.
- 3Combine & Transfer: Turn off heat. Mix cooked pasta into the sauce. Transfer everything to a greased 9‑inch baking dish. Sprinkle mozzarella and Parmesan evenly.
- 4Bake: Preheat oven to 375°F. Bake 18–22 minutes until cheese bubbles and top turns golden brown. Watch for dark spots; cover with foil if it browns too fast.
- 5Rest & Serve: Let the bake rest 5 minutes; this sets the sauce. Garnish with breadcrumbs and parsley if desired. Serve hot.
Recipe Notes
- Chef tip: Sear the pasta briefly in olive oil before pressure cooking for a nutty flavor.
- Best substitution: Swap pumpkin for butternut squash puree; expect a slightly sweeter profile.
- Make-ahead: You can blend sauce and pasta a day ahead; refrigerate and bake fresh for best texture.
- Scaling: Double the recipe for an 8‑serving crowd; use a 12‑inch dish and increase pressure time by 1 minute.
- Troubleshooting: If the bake is watery, uncover for the last 5 minutes of baking to evaporate excess liquid.

Frequently Asked Questions about Instant Pot Pumpkin Pasta Bake: Creamy Fall Dinner
Can I make Instant Pot Pumpkin Pasta Bake without an Instant Pot?
Yes, you can stovetop the pasta and sauce, then bake as directed. Use a large pot for the pasta, simmer the sauce, and combine before baking. The texture may be slightly different but still delicious.
How do I prevent the pumpkin sauce from separating?
Keep the heat low when adding heavy cream and stir constantly. A gradual temperature rise avoids curdling. If separation occurs, whisk in a splash of broth to bring it back together.
What is the best cheese for a gooey top?
A blend of mozzarella for melt and Parmesan for flavor works best. Mozzarella gives stretch, while Parmesan adds a crisp, caramelized edge. Avoid pre‑shredded cheese with anti‑caking agents.
Can I freeze the baked pumpkin pasta bake?
Absolutely. Cool completely, wrap tightly, and freeze for up to two months. Thaw overnight in the fridge, then reheat in the oven covered, adding a splash of milk for moisture.
Why does my bake turn out soggy, and how can I fix it?
Soggy results from overcooked pasta and excess liquid in the sauce. Undercook pasta by one minute, and bake uncovered for the final 5 minutes to evaporate moisture. If already soggy, stir in a bit of breadcrumbs and bake longer.
