Ingredient Notes

• Pumpkin puree: Adds natural sweetness and thickens sauce; substitute with butternut squash puree for a milder flavor, but lose orange color.
• Heavy cream: Provides richness and prevents curdling; coconut milk works for dairy‑free, yet adds coconut flavor.
• Pasta: Use short shapes for even cooking; overcook leads to mushy bake – watch cooking time closely.
• Mozzarella: Creates stretch; low‑fat versions may not melt fully, producing grainy texture.
• Chicken broth: Adds depth; using water makes sauce bland – always season broth.

Add liquids and pasta

Pour in broth, pumpkin puree, heavy cream, then pasta. Stir, seal lid, set Pressure Cook on High 4–5 minutes. Ensure lid is sealed tightly.
