Ingredients

  • 1 lb. breakfast sausage
  • 1 cup chopped yellow onion
  • 3 cups chopped fresh kale
  • 12 ounces English muffins cubed and toasted

  • 10 eggs
  • 2 cups milk
  • 1 tsp. kosher salt
  • ½ tsp. black pepper

Instructions

  • In a large skillet, cook sausage over medium heat until browned and crumbly, about 8 minutes.
  • Add onions; cook, stirring occasionally, until softened, about 5 minutes.
  • Stir in kale; cook, stirring occasionally, 2 minutes. Remove from heat.
  • Add sausage mixture to a 13x9-inch casserole dish.
  • Stir in toasted English muffin cubes and 1 cup cheese.
  • In a medium bowl, beat eggs until smooth. Whisk in milk until combined. Stir in salt and pepper.
  • Pour egg mixture over sausage mixture in casserole dish.
  • Top with remaining 1 cup cheese. Cover with aluminum foil.
  • Refrigerate two hours or overnight.
  • Preheat oven to 350°F.
  • Bake 20 minutes; uncover, and bake until top is toasted, 15 to 20 minutes more. Garnish with parsley, if desired.

Notes

  • Serving this to adults for brunch? Throw in a pinch of crushed red pepper flakes for a kick!
  • To lighten up this casserole, use turkey sausage instead of pork.
  • If you’re not a fan of kale, use tender baby spinach.
  • To toast the English muffins, bake at 400°F for 10 minutes.
  • Use any bread you like, such as sourdough, baguettes, or ciabatta.
  • You can use any cheese you like this recipe; I used a mixture of sharp cheddar and Gruyere.
  • Serve with your favorite fruit salad and biscuits.
