Ingredients
- 12 large eggs – The base that gives our slab its structure and protein power.
- 1/2 cup milk or unsweetened almond milk – Adds a bit of creaminess and helps the eggs bake up fluffy.
- 1 tablespoon olive oil – For sautéing our veggies to perfection.
- 1 small yellow onion, diced – Builds a savory, aromatic foundation.
- 1 red bell pepper, diced – Brings a sweet crunch and a pop of color for that aesthetic food vibe.
- 2 cups fresh spinach, roughly chopped – An easy way to sneak in some greens.
- 1 cup cooked smoked turkey sausage, diced – Provides that hearty, savory breakfast flavor without the pork.
- 1 1/2 cups shredded cheddar cheese – Because everything’s better with melty, gooey cheese.
- 1 teaspoon garlic powder – For a little extra flavor that goes a long way.
- 1/2 teaspoon salt – Enhances all the other flavors.
- 1/4 teaspoon black pepper – Adds a gentle kick.
Step by Step Method
- Preheat your oven to 375°F (190°C) and generously grease a 9×13 inch baking dish with butter or non-stick spray.
- In a large skillet, heat the olive oil over medium heat. Add the diced onion and bell pepper and cook for about 5-7 minutes, until they’ve softened. Throw in the spinach and cook for another minute, just until it wilts. Remove the skillet from the heat.
- In a very large bowl, whisk the eggs, milk, garlic powder, salt, and pepper together until they’re completely combined and a little frothy.
- Stir the cooked veggie mixture, diced turkey sausage, and one cup of the shredded cheese into the egg mixture. Pour everything into your prepared baking dish and spread it out evenly. Top with the remaining half cup of cheese.
- Bake for 25-30 minutes. You’ll know it’s done when the edges are golden brown and the center is completely set (no jiggle when you give the pan a gentle shake).
- Let it cool in the pan for at least 10 minutes before slicing it into 6 or 8 squares. This helps it hold its shape beautifully.
Oven Temperatures for Perfect Baking
Oven temperatures can be finicky, and getting this right is key for a perfect, non-rubbery slab. I always recommend using an oven thermometer to check that your oven is calibrated correctly. If your oven runs hot, it might cook faster and brown too much on top before the center is done. If it runs cool, it might take a few extra minutes. The sweet spot is 375°F. If you only have a convection oven, reduce the temperature by 25 degrees and keep a close eye on it, as it will bake a little faster.
Serving Ideas & Pairings
This slab is a superstar all on its own, but it also plays well with others! For a simple breakfast idea, grab a square and eat it with your hands on the way out the door. For a full brunch recipes spread or a breakfast buffet, serve a couple of squares alongside fresh fruit, a simple arugula salad, or some roasted potatoes. It also pairs wonderfully with a dollop of cool salsa, a scoop of avocado, or a drizzle of hot sauce for those who like a little kick. So versatile.
Flavor Twists for Breakfast Slab
The beauty of this recipe is how easily you can make it your own. For a Mediterranean twist, swap the cheddar for feta, use kalamata olives, and add some dried oregano. If you’re in the mood for something southwestern, use pepper jack cheese, add a can of drained green chiles, and top with a sprinkle of cumin. Not a fan of turkey sausage? Diced cooked chicken or even black beans work wonderfully. Honestly, if you hate mushrooms, leave ‘em out! Use what you love and what you have on hand.
Storage & Reheating Tips
Let the baked slab cool completely before storing. You can keep individual squares in an airtight container in the fridge for up to 4 days. To freeze, wrap each square tightly in plastic wrap and then place them in a freezer bag. They’ll keep for up to 2 months. To reheat, the microwave is fastest (about 60-90 seconds on high), but for the best texture, pop a square in the toaster oven or a regular oven at 350°F for 10-12 minutes until it’s heated through and the edges are crisp again.
Budget-Friendly Tips for Healthy Eating
Eating healthy doesn’t have to break the bank. This recipe is already pretty economical, but here are a few extra tips. Buy block cheese and shred it yourself—it’s cheaper and melts better than the pre-shredded stuff. Wait for turkey sausage to go on sale and stock up for the freezer. You can also bulk up the veggies with even more spinach or add in some chopped mushrooms to make the recipe stretch further without adding much cost. Frozen diced peppers and onions are a great, affordable shortcut, too!
FAQs About Breakfast Slab
- Can I make this recipe without dairy? Absolutely! Just use your favorite non-dairy milk and skip the cheese or use a vegan shred. The eggs will still hold everything together beautifully.
- I need more quick breakfast ideas. Is this good for a crowd? This is one of the best breakfast food options for a crowd! It’s easy to double the recipe and bake it in two pans, making it perfect for a holiday morning or a breakfast buffet where you need plenty of savory breakfast options.
- How do I know the center is fully cooked? The best test is the jiggle test. If the center jiggles like jello, it needs more time. It should be completely firm. You can also insert a knife into the center; if it comes out clean, you’re good to go.
- Can I add potatoes to this? You sure can! For the ultimate breakfast inspo, add about two cups of frozen shredded hash browns (thawed and squeezed dry) to the egg mixture for a heartier slab.
And that’s it! You’re all set to conquer your week with this incredible Easy High-Protein Breakfast Slab.
