Steps
- 1
Heat a stainless steel pan over high heat. Add the turkey sausage, smash it into the bottom of the pan, and let it cook on one side for a few minutes. Then break it apart and cook it through. Move the sausage to the side.
- 2
Add the diced shallot and the frozen spinach to the pan. Sauté until the shallot softens and the spinach melts, then mix everything together with the sausage.
- 3
In a bowl, whisk the eggs, milk, cottage cheese, black pepper and spicy brown mustard together.
- 4
Cut the sourdough into big cubes and shred the cheese.
- 5
Rub butter all over an 8x8 baking dish. Spread most of the bread cubes over the bottom, add all of the sausage mixture, and top with the rest of the bread cubes.
- 6
Pour the egg base over everything. If it doesn't fill the pan, beat in an extra egg or two. If you use a 9x13 pan, add a few extra eggs or more bread.
- 7
Top with the shredded cheese and bake at 350°F for 30-40 minutes. Start checking at 20-25 minutes. It's done when the middle is cooked through and no longer looks soupy.
- 8
Let the casserole cool completely so it cuts into clean slices.
- 9
For the egg sauce, mix the ketchup, mayo and hot sauce together. A squeeze bottle makes it easy to drizzle.
- 10
Cut the casserole into 6 pieces. To reheat a piece, microwave it for about 1 minute, then crisp the bottom in a nonstick pan.
- 11
Drizzle with the egg sauce and finish with sliced chives.
Creator's notes
This video makes three casseroles: breakfast, a King Ranch–style lunch, and a red wine braised beef cottage pie. This card covers the breakfast casserole. Ethan prices the full pan at $16.04, or $2.67 a slice across 6 slices. Each slice with sauce is about 488 calories and 35 g protein. Let it cool fully before slicing for cleaner pieces.
