Ingredients
Pasta
- 1 Pound Large Elbow Macaroni
Sauce & Flavorings
- 3 Tablespoons Unsalted Butter
- 1 Large Shallot, finely chopped
- 4 Cloves Garlic, mashed
- 1 4 Ounce Can Diced Green Chilis
- 1 1/2 Teaspoons Smoked Paprika
- 1/3 Cup All-Purpose Flour
- 2 Cups Whole Milk
- 1 Cup Heavy Cream
- 1 Tablespoon Dijon Mustard
- Kosher Salt, to taste
- Ground Black Pepper, to taste
Cheese & Topping
- 4 Cups Shredded Cheddar Cheese
- 1 1/4 Cup Parmesan Cheese, freshly grated
- 1 1/2 Cups Panko Breadcrumbs
Instructions
- Prepare Pasta: Cook the elbow macaroni according to the package instructions until al dente. Drain well and set aside to keep warm.
- Heat Pan: Place a large skillet on the stove over medium heat to prepare for making the cheese sauce.
- Melt Butter: Add the unsalted butter to the hot skillet and allow it to melt completely.
- Cook Shallot and Garlic: Add the finely chopped shallot and mashed garlic to the melted butter, cooking for 1-2 minutes until fragrant and slightly softened. Then stir in the diced green chilis, mixing well.
- Prepare Roux: Sprinkle the smoked paprika and all-purpose flour over the butter, shallot, garlic, and chili mixture. Stir continuously to coat and cook the flour; the mixture will thicken and form a roux.
- Add Milk and Cream: Gradually pour in the whole milk, heavy cream, and Dijon mustard while stirring constantly to combine everything smoothly. Let the sauce cook and thicken for 3-4 minutes, stirring regularly. Season with kosher salt and ground black pepper to taste.
- Add Cheese: Remove the skillet from heat and stir in 3 cups of shredded cheddar cheese and the freshly grated Parmesan cheese. Mix gently until the cheese melts into a smooth sauce.
- Prepare Tray: Spray a half baking sheet (18 x 13 inches) with non-stick cooking spray to prevent sticking.
- Add Pasta to Tray: Spread the cooked elbow macaroni in an even layer across the prepared baking sheet.
- Add Breadcrumbs and Sauce: Evenly sprinkle 1 cup of the panko breadcrumbs over the pasta. Pour the prepared cheese sauce over the pasta and breadcrumbs.
- Toss Pasta and Breadcrumbs: Gently toss the pasta and crumbs in the cheese sauce to coat everything evenly, ensuring a balanced distribution of flavors and textures.
- Add Remaining Breadcrumbs and Cheese: Sprinkle the remaining 1/2 cup of panko breadcrumbs over the top of the pasta, then add the remaining shredded cheddar cheese to create a topping that will crisp as it broils.
- Transfer to Oven: Place the baking sheet approximately 6 to 7 inches below the broiler in your oven.
- Broil Mac n Cheese: Broil for 5-6 minutes, watching closely to brown the top evenly and crisp the breadcrumbs. Rotate the tray as needed under the broiler for uniform cooking and to prevent burning.
- Serve and Enjoy: Remove from the oven and let the mac and cheese cool slightly before serving. Enjoy the creamy, cheesy, and crispy sheet pan chili mac n cheese!
Notes
- Use freshly grated Parmesan cheese for the best texture and flavor in the cheese sauce.
- Keep a close eye while broiling to prevent burning the panko topping.
- For a spicier dish, substitute the diced green chilis with jalapeños or add crushed red pepper flakes.
- This recipe works well with other pasta shapes like shells or cavatappi if elbow macaroni is unavailable.
- To make ahead, prepare everything up to broiling, cover, and refrigerate. Broil just before serving.
