- cooking spray
- 1 pound Italian sausage
- 2 bell peppers chopped (about 2 cups total)
- 1 onion chopped (about 1 cups)
- 10 eggs

Preheat the oven to 375°F and spray a 9×13-inch baking dish with cooking spray.
Cook the sausage in a large skillet over medium-high heat until fully browned. Transfer to a towel-lined plate.
Sauté the bell peppers and onion in the same skillet until softened, about 10 minutes, then remove from the heat.
Whisk the eggs, milk, Dijon mustard, salt, and pepper in a large bowl until smooth.
Stir in the sausage, pepper mixture, frozen potatoes, and black beans into the egg mixture
Fold in ¾ cup of the Cheddar cheese and 3/4 cup of the pepper Jack cheese.
Transfer the mixture to the baking dish and top with the remaining cheese.
Cover with foil and bake for 40 minutes then remove the foil and cook for an additional 5-10 minutes or until set and golden. Garnish with chives, and serve.
Chef Jenn’s Recipe Notes
- I’ve tested this recipe with shredded potatoes and diced potatoes. The diced hold up much better. The shreds dissolved in the casserole, giving it a grainy texture. Look for the small dice, and keep them frozen.
- Italian sausage has the best flavor in this recipe, but you could totally swap in breakfast sausage instead. Use bulk sausage if you don’t want to mess with removing the casings from links.
- Cooking time is going to vary, but give this some time. You don’t want to cook it at too high a temperature or it’ll get too brown on the bottom.
