Smoked Mac and Cheese Recipe Pellet Grill: Silky Three-Cheese Blend With Wood-Fired Depth

There’s nothing like the aroma of wood smoke infusing a creamy mac and cheese on the pellet grill. I developed this method to blend silky cheese sauce with deep, smoky flavor.

This approach transforms a classic side into something extraordinary. The three-cheese blend melts beautifully while the pellet grill adds that signature wood-fired depth without overpowering the dish.

The cheese selection defines this dish. Sharp cheddar provides tang, Gruyère adds nutty complexity, and Parmesan delivers umami depth. Whole Foods or Murray’s Cheese offer excellent pre-selected blocks. Always grate cheese fresh—pre-shredded contains anti-caking agents that prevent smooth melting. For the milk, whole fat is non-negotiable for that silky texture.

No pellet grill? Liquid smoke at one-quarter teaspoon approximates the flavor, though it lacks depth. Annie’s vegetarian Worcestershire replaces traditional versions containing anchovies. For cheese substitutions, Gouda works well in place of Gruyère, and Pecorino Romano can swap for Parmesan. The smoked paprika can be omitted, but it significantly enhances the wood-fired character.

The sauce thickens as it cools—reheat gently with additional milk. Store leftovers in an airtight container for up to 5 days refrigerated. For longer storage, freeze before adding pasta (sauce only) for up to 3 months. The smoked flavor intensifies over time, so consider this when meal prepping.

Step-by-Step Instructions for Smoked Mac and Cheese Pellet Grill

Master the technique for velvety cheese sauce with authentic wood-fired flavor on your pellet grill.

Step 1: Cook the Pasta to Al Dente Perfection

Bring a large pot of salted water to a rolling boil. Add the 1 lb Elbow Macaroni and cook according to package directions for al dente texture, typically 1 minute less than the recommended time. You want the pasta slightly firm as it will continue cooking when baked.

Drain the pasta immediately and rinse briefly under cold water to stop the cooking process. Toss with a small amount of the 0.5 cup Unsalted Butter to prevent sticking. The starch on the pasta surface will help the cheese sauce cling beautifully later.

Step 2: Create a Silky Béchamel Base on the Grill

In a heavy saucepan suitable for stovetop use, melt the remaining 0.5 cup Unsalted Butter over medium heat on your pellet grill. Whisk in the 0.33 cup All-Purpose Flour to form a smooth roux. Cook for 2-3 minutes, stirring constantly, until the mixture turns a light golden color and emits a nutty aroma.

Gradually whisk in the 3 cups Whole Milk, adding it in a slow stream to prevent lumps. Continue whisking until the mixture thickens enough to coat the back of a spoon, about 5-7 minutes. This béchamel forms the luxurious foundation for your cheese sauce.

Step 3: Build the Three-Cheese Sauce with Depth

Reduce heat to low and add the 1 tbsp Dijon Mustard, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Salt, 0.5 tsp Black Pepper, and 0.5 tsp Smoked Paprika. Stir for 1 minute to allow the spices to bloom in the warm sauce.

Remove from heat and add the 8 oz Sharp Cheddar Cheese, 4 oz Gruyère Cheese, and 2 oz Parmesan Cheese, all freshly grated. Stir until completely melted and smooth. Finish with the 1 tsp Worcestershire Sauce for a subtle umami depth that complements the smoke flavor.

Step 4: Combine and Smoke to Perfection

Fold the cooked pasta into the cheese sauce until every piece is thoroughly coated. Transfer the mixture to a greased baking dish suitable for your pellet grill. The sauce should be glossy and thick, with visible cheese strands when lifted with a spoon.

Smoke at 225°F for 45-60 minutes until the top develops a light golden crust and the edges bubble. The smoke will infuse the dish with a subtle wood-fired complexity that elevates the three-cheese blend to new heights.
