How to Make It

Start by preparing the cheese sauce and burgers for a delicious meal.

Melt the butter

Melt the butter in a small saucepan over medium heat. Add the flour and whisk to combine. Continue whisking for one minute.

Whisk in milk

While continuing to whisk, gradually drizzle in the milk. Once fully added, switch to a wooden spoon and cook over medium heat until the mixture has thickened. Never let it come to a boil.

Stir in cheese

Remove from the heat and add the shredded cheese. Stir to combine and melt the cheese. Stir in the Dijon mustard. Taste, then season as needed with salt and pepper. Cover to keep warm and set aside.

Cook the veggies

Heat a large skillet over medium heat. Add the vegetable oil, then the onions and peppers. Toss to coat with the oil and season with salt and pepper. Cook for 5 to 8 minutes until the onions are translucent and the peppers are softened. Remove with a slotted spoon to a bowl, reserving the oil in the skillet. Cover to keep warm.

Form patties

Form the ground beef into four patties. Sprinkle both sides with kosher salt.

Cook the patties

Cook in the skillet over medium-high heat for 3 to 5 minutes on each side until they reach the desired doneness.

Assemble the burgers

Place one burger bun half on each of four plates. Top each with a burger patty, then some of the onion/pepper mixture, a dollop of cheese sauce, and finally the top of the burger bun. Serve with fries.

How to Store It

Fridge: Store for up to 3 days in an airtight container.
Freezer: No, the texture changes when frozen.
Reheat: Microwave on medium for 1-2 minutes.

Tips for Best Results
