Ingredients You’ll Need

Eggs, lean turkey sausage, cottage cheese, and a colorful mix of vegetables make this a protein-rich sheet pan bake. Everything is naturally gluten free and easy to customize.

• 1 tbsp olive oil, for greasing pan
• 12 large eggs
• 1 cups liquid egg whites
• 12 oz turkey breakfast sausage, cooked and crumbled
• 1 cups low-fat cottage cheese, small curd
• 1 cups shredded cheddar cheese
• 1 cups diced bell peppers, mixed colors
• 2 cups baby spinach, chopped
• 1/2 cups red onion, finely chopped
• 1 cups cherry tomatoes, halved and patted dry
• 1/2 tsp garlic powder
• 1/2 tsp smoked paprika
• fine sea salt, to taste
• black pepper, to taste

How to Make the Breakfast Squares

Prep the pan, whisk, pour, and bake until just set, then slice and store.

1. Preheat the oven to 375°F (190°C). Lightly oil an 18×13-inch rimmed sheet pan and line with parchment, then brush the parchment with a little oil.
2. Cook the turkey sausage in a skillet over medium heat, breaking it up with a spoon, until browned and cooked through, 5 to 7 minutes. Set aside to cool slightly.
3. In a large bowl, whisk the eggs and egg whites until smooth. Whisk in cottage cheese, garlic powder, smoked paprika, a pinch of salt, and several grinds of pepper.
4. Stir in the cooked sausage, bell peppers, spinach, red onion, half of the cheddar, and the cherry tomatoes. Fold gently to distribute evenly.
5. Pour the mixture into the prepared sheet pan and spread the solids evenly so each slice gets a bit of everything. Tap the pan once on the counter to release air bubbles.
6. Sprinkle the remaining cheddar over the top.
7. Bake on the middle rack until the edges are puffed, the top is lightly golden, and the center is just set, 18 to 22 minutes. Check at 18 minutes; do not overbake.
8. Cool in the pan for 10 minutes, then use the parchment to slide the bake onto a cutting board.
9. Slice into 8 squares. Serve warm, or cool completely for meal prep.
10. Store in airtight containers in the fridge for up to 4 days or freeze individually wrapped squares for up to 2 months.

Smart Storage, Make-Ahead, and Reheating

Cool the baked squares for 10 minutes, then slice and store in airtight containers for up to 4 days in the fridge. For longer storage, wrap individual pieces and freeze up to 2 months. Thaw overnight in the fridge.

Reheat in the microwave for 45 to 60 seconds or in a 350°F (175°C) oven for 8 to 10 minutes until warmed through. These also taste great cold packed into a lunchbox. If you travel a lot, these pack well with an ice pack; for more portable ideas, see gluten free hotel and travel breakfasts.

Common Mistakes to Avoid

• Overbaking the eggs: Pull the pan when the center is just set and edges are lightly golden. Residual heat finishes the job and keeps the texture tender.
• Using too much watery veg: Tomatoes and zucchini can water out. Pat them dry or roast briefly first to avoid a soggy bake.
• Skipping the pan prep: A well-oiled and parchment-lined pan guarantees easy release and clean slices.
• Heavy-handed salt: Cottage cheese and sausage are already salty. Taste the mixture before adding more salt.
• Uneven chopping: Keep vegetable pieces small and similar in size for even cooking and clean cuts.

Variations and High-Protein Swaps

• Swap the meat: Use crumbled chicken sausage, ham, or smoked salmon. Keep portions similar to maintain protein levels.
• Dairy-free: Replace cottage cheese and cheddar with unsweetened almond milk ricotta and a dairy-free cheddar-style shred.
• Veggie trio: Try broccoli, mushrooms, and scallions, or use roasted asparagus in spring.
• Spice profiles: Add Italian seasoning, taco seasoning, or a pinch of red pepper flakes for heat.
• Extra protein boost: Stir in 1/2 cup shredded cooked chicken breast or fold in more egg whites.
• Mediterranean: Use feta, olives, spinach, and roasted red peppers. Season with oregano.
• Southwest: Add black beans, corn, cheddar, and salsa on the side.
• Caprese: Cherry tomatoes, basil, and mozzarella. Finish with a drizzle of balsamic after baking.
• Mini muffin version: Divide the mixture into a greased 12-cup muffin tin and bake 16 to 20 minutes.

What to Serve With These Breakfasts

Round out the plate with fresh fruit, a handful of grapes, or half an avocado for extra fats and fiber. A small gluten free toast with butter or nut butter works if you want more carbs before a workout.

For weekend brunch, pair the egg squares with a simple arugula salad dressed in lemon and olive oil. If pancakes are on the menu too, browse these weekend gluten free breakfast ideas and mix and match.

Your Questions, Answered

How do I know the egg bake is done without overcooking?

Bake until the center looks just set and no longer jiggles when you nudge the pan. A thin knife inserted in the center should come out mostly clean with a few moist bits. Pull it then, and let carryover heat finish it.

Can I make this without cottage cheese?

Yes. Replace cottage cheese with 1 cup ricotta or 3/4 cup unsweetened Greek yogurt. The texture stays creamy and you still get a nice protein boost.

Are oats really gluten free for celiacs?

Use certified gluten free oats from a producer that prevents cross-contact. Not everyone tolerates oats the same way, so start small and see how you feel. I linked a detailed guide above.

What’s the best way to freeze and reheat single portions?

Cool completely, wrap each square tightly, and freeze in a zip-top bag. Thaw overnight in the fridge, then microwave 60 to 90 seconds or bake at 350°F (175°C) for about 10 minutes.

How can I add even more protein without changing flavor too much?

Whisk in an extra 1/2 cup egg whites or fold in finely diced cooked chicken breast. You can also top slices with a spoonful of Greek yogurt for a creamy finish.
