Step 1

Set a large 12-inch skillet over medium-high heat.

Step 2

Add ground beef and onion to the skillet and season lightly with kosher salt and black pepper.

Step 3

Break up the meat as it cooks and cook until it's brown in color and no pink remains. Drain the meat and set aside.

Step 4

In the same pan as you used to brown the meat, set it over medium heat and add the butter.

Step 5

Melt the butter and sprinkle in the flour and whisk together until it forms a paste.

Step 6

Let it bubble slightly and cook for about a minute.

Step 7

Slowly stream in milk and whisk until thick. This might take a few minutes to get the gravy as thick as you like.

Step 8

Add cooked beef and onion to the white gravy mixture.

Step 9

Season with salt and pepper to taste. Feel free to add more flavor by sprinkling in crushed red pepper, garlic powder or fresh herbs.

Step 10

Serve over toast.
