Ingredients
For the Pasta
- 12 ounces elbow macaroni or cavatappi
- 1 tablespoon salt, for the pasta water
- 1 teaspoon olive oil, optional
For the Lobster
- 12 ounces cooked lobster meat, roughly chopped
- 1 tablespoon unsalted butter
- 1 small garlic clove, minced
- 1 teaspoon fresh lemon juice
- ¼ teaspoon freshly ground black pepper
- 1 tablespoon chopped fresh parsley, optional
For the Pumpkin Cheese Sauce
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 2 cups whole milk, warmed
- 1 cup pumpkin puree, unsweetened
- 1½ cups shredded sharp cheddar cheese
- 1 cup shredded Gruyère cheese
- ½ cup grated Parmesan cheese
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon smoked paprika
- Salt and black pepper, to taste
For the Crispy Topping
- ¾ cup panko breadcrumbs
- 2 tablespoons melted butter
- 2 tablespoons grated Parmesan cheese
- 1 tablespoon chopped fresh parsley, optional
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a medium baking dish with butter or cooking spray.Grate the cheddar and Gruyère cheese if they are not already prepared. Freshly grated cheese generally melts more smoothly than pre-shredded cheese because it contains less added anti-caking material.
- Bring a large pot of salted water to a boil. Add the macaroni and cook until it is just shy of al dente, following the package instructions.The pasta should remain slightly firm because it will continue cooking in the oven. Drain thoroughly and set aside. Avoid overcooking the macaroni, as soft pasta can become mushy after baking.
- Melt 1 tablespoon of butter in a skillet over medium-low heat. Add the minced garlic and cook for about 30 seconds until fragrant.Add the cooked lobster meat, black pepper, and lemon juice. Gently toss for 1–2 minutes, just until warmed through. Remove from the heat and set aside.Do not cook the lobster for too long at this stage. Excessive heat can make it tough and rubbery, especially if it is already fully cooked.
- In a large saucepan, melt 2 tablespoons of butter over medium heat. Sprinkle in the flour and whisk continuously for approximately 1–2 minutes.The mixture should form a smooth paste and smell slightly nutty, without becoming dark brown. This butter-and-flour mixture, known as a roux, helps thicken the cheese sauce.
- Gradually pour in the warm milk, whisking constantly to prevent lumps. Continue cooking for 3–5 minutes until the mixture begins to thicken.Add the pumpkin puree, Dijon mustard, garlic powder, onion powder, smoked paprika, and optional nutmeg. Stir until the sauce is smooth and evenly colored.Keep the heat at medium-low once the sauce thickens. A gentle simmer is sufficient; vigorous boiling may cause the sauce to become uneven.
- Reduce the heat to low. Add the cheddar, Gruyère, and Parmesan a handful at a time, stirring after each addition until melted.Taste the sauce and adjust the salt and black pepper. Remember that the cheeses already contain salt, so season gradually.If the sauce is too thick, add a small splash of milk. The finished sauce should be creamy enough to coat the back of a spoon.
- Add the drained macaroni to the cheese sauce and stir until every piece is coated. Gently fold in most of the prepared lobster, reserving a few pieces for the top if desired.Transfer the mixture to the prepared baking dish and spread it evenly. Arrange the reserved lobster pieces over the surface for an attractive presentation.
- In a small bowl, combine the panko breadcrumbs, melted butter, Parmesan cheese, and optional parsley.Sprinkle the mixture evenly over the macaroni. The buttery breadcrumbs create a crisp contrast to the soft pasta and creamy pumpkin cheese sauce.
- Bake uncovered for approximately 15–20 minutes, until the sauce is bubbling around the edges and the topping is lightly golden.For extra browning, place the dish under the broiler for 1–2 minutes, watching carefully to prevent burning.If your lobster is already cooked, avoid unnecessarily extending the baking time. The goal is to heat the dish through without drying out the seafood.
- Remove the dish from the oven and let it rest for 5 minutes. This allows the sauce to settle slightly and makes serving easier.Garnish with fresh parsley, a little extra Parmesan, and a squeeze of lemon if desired. Serve warm while the cheese sauce is creamy and the breadcrumb topping is crisp.
Notes
- Use fully cooked lobster carefully: If your lobster is already cooked, warm it gently before adding it to the pasta. Overcooking can make it tough.
- Choose the right pumpkin: Plain pumpkin puree gives the sauce a smooth consistency and mild earthy flavor.
- Shred cheese at home: Freshly shredded cheese usually melts more evenly than pre-shredded varieties.
- Cook pasta slightly under al dente: The macaroni continues cooking in the oven, so avoid making it too soft on the stovetop.
- Adjust the sauce consistency: Pumpkin and cheese can thicken the sauce considerably. Keep extra milk available to loosen it if needed.
- Use a flavorful cheese blend: Sharp cheddar provides tang, Gruyère adds nuttiness, and Parmesan contributes a savory finish.
- Add lemon at the end: A little lemon juice brightens the richness of the cheese and lobster without overpowering the dish.
- Handle leftovers safely: Refrigerate leftovers in a shallow, airtight container within two hours of cooking and consume within 3–4 days.
