Golden baked pumpkin pasta with bubbling cheese

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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
