Here Are the Easy Steps for Making Smooth, Creamy, Lump-Free Gravy

1. Place a large skillet over medium heat; add the butter or margarine to your pan drippings, such as would come from browning sausage in the skillet. (If you don’t have any pan drippings to begin with, that’s ok.  Just start by melting your butter or margarine and proceeding as below.)

2. Melt the butter, stirring it into the sausage drippings; add the flour, stirring constantly until this mixture turns from white in color to more of a tan color, ensuring that your flour is fully cooked.

3.  Here’s the BIG SECRET for making lump free gravy: Remove the skillet from the heat before you go any further with the gravy-making process!

4.  Now, very slowly whisk in the evaporated milk (or whatever liquid you happen to be using to make a gravy at any other time), a little a time, whisking constantly, never adding more milk until what you’ve added if fully incorporated.  Now whisk in the milk in the same way.

5.  Now, finally return the skillet of gravy to the burner over medium heat; season the gravy to taste, as desired, whisking until the gravy is simmering and nicely thickened.

Breakfast Casserole

  • 8 slices rye and pumpernickel bread (this is usually rye bread that has a pumpernickle swirl within each slice) buttered on each side
  • 2 cups whipping cream
  • 2 1/2 cups shredded sharp cheddar cheese
  • 8 large eggs, beaten
  • 1 tsp. kosher salt
  • 1 tsp. black pepper
  • 1 lb. sausage cooked and crumbled, fats drained

Country Gravy

  • 1/2 lb. sausage cooked, crumbled, and keeping the fats in the skillet with the sausage
  • 1/2 cup butter, oil, or margarine
  • 1/2 cup all-purpose flour
  • 12 oz can evaporated milk
  • 2-3 cups milk
  • red pepper flakes, salt, and pepper to taste


Make the Breakfast Casserole

  • Preheat the oven to 350 degrees F.
  • In a large mixing bowl, combine the whipping cream with 1 1/2 cups of the cheese, eggs, salt, and pepper, stirring well to combine.
  • Place the buttered bread across bottom of a greased 9 x 13 pan; top the bread with half of the cooked sausage crumbles.
  • Pour the prepared egg mixture over the sausage layer, then top with the remaining half of the sausage; sprinkle remaining 1 cup of cheese over all.
  • Cover the casserole with foil, placing it into fridge to rest overnight, or 8-10 hours. **FYI – This is a very important step, I’ve discovered. Don’t be tempted to skip it if you desire a tender and delicate breakfast casserole.
  • When ready to bake, remove the breakfast casserole from the fridge and uncover; let the casserole rest on the counter for 40-45 minutes to remove the chill.
  • Preheat the oven to 350 degrees F.
    Bake the casserole, uncovered, for 30-35 minutes, or until a knife inserted into center comes out clean. (If the casserole is still clinging to the knife when you do this test, cook the casserole for an additional few minutes until the knife test is successful.)
  • When the casserole is fully cooked, remove it from the oven and let it rest for 5 minutes. Cut into squares and serve topped with warm country gravy.

Make the Country Gravy

  • In the skillet with the cooked and crumbled sausage and the pan drippings, over medium heat, add the butter or margarine letting it melt.
    Add the flour, stirring constantly until this mixture turns from white in color to more of a tan color, cooking it just a minute or two. The mixture will be very thick and lumpy at this point.
    remove the skillet from the heat. (very important!)Remove the skillet from the heat!
  • Remove the skillet from the heat completely. Slowly add the evaporated milk, a little at a time, whisking constantly, never adding more milk until what you’ve added is fully incorporated. Now whisk in the regular milk in the very same way.
  • Now, return the skillet of gravy to the burner over medium heat; season the gravy to taste with salt, pepper, and red pepper flakes, as desired, whisking the gravy until it’s creamy, thickened, and simmering.

Hi Chef Alli. A variation of one of my favorite go to casseroles. I love rye/pumpernickel breads! I’ve never buttered my bread before making— will have to try this. I did notice in the instructions that they say to UNcover and put in the fridge overnight I think you meant COVER? I’ll try this one for Christmas weekend. Wishing you and your family a Merry Christmas~Blessings for the New Year! Sid
