This pumpkin mac and cheese recipe is a stovetop fall dinner made with smoked Gouda, extra sharp cheddar, pumpkin puree, and a bacon fat roux for a velvety, deeply savory sauce ready in 30 minutes. This is a cottage kitchen autumnal pasta dish that earns its place on the dinner table every single year.
Cook the pasta – Bring a large pot of generously salted water to a boil. Cook macaroni until just al dente, about 8 to 10 minutes. Reserve 1 cup pasta water before draining. Drain and set aside.
Make the roux – Melt bacon fat in a large saucepan over medium-low heat. Add flour and stir constantly for 1 to 2 minutes until smooth and slightly golden.
Build the sauce – Gradually pour in milk in a slow steady stream, whisking constantly. Whisk over medium-low heat until thickened and smooth, about 3 to 4 minutes.
Add pumpkin and cheese – Stir in pumpkin puree, smoked gouda, and extra sharp cheddar. Stir over medium-low heat until both cheeses are fully melted and sauce is glossy. Season with salt, pepper, and cayenne if using.
Fold in pasta – Add drained pasta and fold gently until every noodle is evenly coated. Add reserved pasta water a splash at a time if sauce is too thick.
Serve – Serve immediately topped with extra shredded gouda, crumbled bacon, or a brown butter sage drizzle.
Notes
Grate cheese fresh – Pre-shredded cheese contains anti-caking agents that prevent smooth melting and produce a grainy sauce. Always grate from block.Keep heat at medium-low – High heat causes dairy sauces to break and separate. Medium-low throughout produces a smooth, velvety result.Reserve pasta water – Add a splash if the sauce thickens too much after folding in the pasta.Serve immediately – Stovetop mac and cheese thickens quickly as it sits. Serve the moment the pasta is folded into the sauce.
