This sheet pan egg bake has 37 grams of protein per serving and takes 55 minutes start to finish, most of it hands-off in the oven. The protein comes from eggs, turkey sausage, cottage cheese, and cheddar, not a scoop of powder, so it tastes like an actual breakfast casserole.
I started making this on weeks when I don’t have time to fry eggs one batch at a time for two kids who don’t care about macros and just want something warm before school. Sauté the peppers and onion, brown the sausage, mix it all with the eggs in one bowl, and pour it into a pan.
The cottage cheese is the trick here, the same low-key ingredient that powers these cottage cheese pancakes. It disappears into the eggs as it bakes and adds almost 25 grams of protein to the whole pan without any sour flavor coming through.
Each serving lands around 300 grams of food, so this counts as an actual meal, not a snack-sized square you’ll be hungry again by 10 a.m.
Why You’ll Love This Recipe
- Delivers 37 grams of real protein per serving, no powder involved
- One bowl and one pan means less cleanup on a busy morning
- Reheats well for grab-and-go breakfasts all week
- Turkey sausage and cottage cheese keep it lighter than an all-cheese version
Ingredient Notes
- eggs: Use large eggs. They’re the backbone of the protein here, about 6g each.
- cottage cheese: Low-fat (2%) cottage cheese whisks in smooth and adds close to 25g protein to the whole pan. Ricotta works as a swap but has less protein per cup.
- turkey breakfast sausage: Adds about 45g protein to the pan with less grease than pork sausage. Regular pork breakfast sausage works too, just drain more fat off.
- sharp cheddar cheese: Sharp cheddar gives more flavor per gram than mild, so you don’t need to pile it on.
- red bell pepper: Adds sweetness and color. Green pepper works but tastes more bitter once baked.
- yellow onion: Turns sweet as it cooks down. White onion is a fine swap with a sharper bite.
- olive oil: Just enough to keep the vegetables from sticking before they hit the egg mixture.
- smoked paprika: Gives the eggs a faint smoky note without adding heat.
- chives: Optional garnish. Adds color and a mild oniony bite right before serving.
Sheet Pan Egg Bake with Peppers, Onion, and Turkey Sausage
Ingredients
Method
- Heat oven to 375 F / 190 C. Grease a 9x13-inch / 23x33 cm rimmed sheet pan and line with parchment paper, letting the edges hang over the sides.
- Heat olive oil in a 10-inch / 25 cm skillet over medium heat. Add onion and bell pepper and cook for 5 to 6 minutes, stirring occasionally, until the onion turns translucent.
- Add the turkey sausage to the skillet, breaking it up with a spatula. Cook for 6 to 7 minutes until no pink remains and the sausage is lightly browned. Drain any excess liquid.
- Whisk eggs, cottage cheese, garlic powder, smoked paprika, salt, and pepper in a large bowl until mostly smooth. Small curds of cottage cheese are fine.
- Stir the sausage and pepper-onion mixture into the egg mixture along with half the shredded cheddar.
- Pour the mixture into the prepared sheet pan and spread into an even layer with a spatula.
- Scatter the remaining cheddar over the top.
- Bake for 22 to 25 minutes, until the eggs are set and the center reaches 160 F / 71 C on an instant-read thermometer and no longer jiggles when you nudge the pan. If the center still moves like loose gelatin at 25 minutes, give it another 3 to 5 minutes rather than pulling it early.
- Let the bake cool in the pan for 5 minutes. Lift it out using the parchment overhang, sprinkle with chives, and cut into 5 pieces.
Notes
- Grease the pan well, egg sticks harder than pancake batter
- Don't skip draining the sausage, extra grease pools under the eggs
- Let cool 5 minutes before cutting or the squares fall apart
- Swap turkey sausage for pork if that's what's in the freezer
Tips for Success
- Whisk the cottage cheese into the eggs first so the curds break down before the meat and vegetables go in
- Drain the cooked sausage well on paper towels or the bake will turn watery in the middle
- Check the center with an instant-read thermometer at 22 minutes and pull the pan once it hits 160 F / 71 C
- Let the bake rest 5 minutes before slicing so the squares hold together instead of falling apart
- Dice the onion and pepper the same size as the sausage crumbles so every bite gets a little of everything
Variations
- Swap the turkey sausage for diced ham or crumbled bacon for a smokier, saltier bake
- Use pepper jack instead of cheddar and add a diced jalapeno for a spicier version
- Stir in a cup of chopped spinach or kale with the peppers for extra vegetables without changing the protein count
Storage and Reheating
Store leftover squares in an airtight container in the fridge for up to 4 days.
Reheat a piece in the microwave for 60 to 90 seconds on medium power, or in a 325 F / 165 C oven for about 10 minutes, until the center feels warm to the touch.
This bake freezes well. Wrap individual squares in plastic then foil, freeze up to 2 months, and reheat straight from frozen in a 325 F / 165 C oven for 20 to 25 minutes.
Serving Suggestions
Serve a square next to a slice of toast with butter, or over a handful of greens dressed with just lemon and salt.
A dollop of plain Greek yogurt or a spoonful of salsa on top adds a cool contrast to the warm eggs.
For a bigger spread, set out hot sauce, sliced avocado, and fresh fruit so everyone can build their own plate.
FAQ
Why is my sheet pan egg bake watery in the middle?
This usually means the sausage wasn’t drained well or the bake came out before the center set. Excess grease and liquid pool under the eggs as they cook, keeping the middle loose even after the edges look done. Drain the sausage on paper towels and pull the pan only once the center hits 160 F / 71 C and no longer jiggles.
Can I use ricotta instead of cottage cheese in this egg bake?
Yes, ricotta works and gives a slightly creamier texture. It has less protein per cup than cottage cheese, so you’ll lose a few grams of protein per serving. Cottage cheese also blends smoother into the eggs, so ricotta may leave slightly visible flecks.
Can I freeze this peppers and onion egg bake?
Yes, this egg bake freezes well for up to 2 months once fully cooled. Wrap individual squares tightly in plastic and foil, then reheat straight from frozen in a 325 F / 165 C oven for 20 to 25 minutes. Skip the microwave for frozen pieces since the edges cook faster than the center.
What goes well with this sheet pan egg bake for breakfast?
Toast, fresh fruit, or a side salad with lemon dressing all work well alongside it. A dollop of plain Greek yogurt or salsa on top adds contrast without adding much prep. It also holds up fine on its own as a grab-and-go breakfast.
Is this sheet pan egg bake gluten free?
Yes, as written this recipe is gluten free since eggs, cottage cheese, cheddar, sausage, and vegetables don’t contain wheat. Double-check your turkey sausage label though, since some brands add fillers with gluten. Everything else in the ingredient list is naturally gluten free.
What’s the difference between this egg bake and a frittata?
A frittata usually starts on the stovetop in a skillet and finishes under the broiler or in the oven, while this egg bake goes straight into a sheet pan and bakes the whole way through. The sheet pan format also makes it easier to cut into even squares for meal prep instead of wedges, unlike these high-protein baked egg cups, which portion themselves from the start.
