Preheat your oven to 350°F. While the oven heats, prepare all your ingredients: finely dice the bell peppers into 1/4-inch pieces (this size ensures even cooking and a better texture in the final bite), cook the bacon until crispy then crumble it, and shred the cheddar cheese fresh—I find that freshly shredded cheese melts much more smoothly than pre-packaged varieties. Have the turkey ready as well. This mise en place approach means you won't be scrambling mid-recipe and everything will come together quickly once you start assembling.

In a large mixing bowl, whisk together the 12 eggs with the milk, salt, pepper, and garlic powder until well combined and smooth. The milk adds richness and helps the eggs set evenly—I recommend using whole milk with higher protein content as it creates a creamier, more substantial bite. Set the mixture aside while you prepare the muffin tin.

Spray a standard 12-cup muffin tin thoroughly with cooking spray, making sure to coat the bottom and sides of each cup—this is crucial for easy release after baking. Divide the cooked bacon, diced bell peppers, turkey, and shredded cheddar cheese evenly among all 12 cups, distributing them as evenly as possible so each bite has balanced flavors and textures.

Carefully pour the egg mixture from Step 2 into each muffin cup until about 3/4 full—this leaves room for the eggs to puff up slightly as they cook without overflowing. Using a fork, gently stir the egg mixture within each cup to evenly distribute the fillings and ensure the cheese and meat are well incorporated throughout the egg base.

Place the muffin tin in the preheated 350°F oven and bake for 12 to 18 minutes, depending on your oven. The egg bites are done when a toothpick inserted in the center comes out clean and the tops are set but still slightly moist—they'll continue to set as they cool. Start checking around the 12-minute mark to avoid overcooking, which can make them rubbery.

Remove the muffin tin from the oven and let the egg bites cool for about 3 to 5 minutes—this brief rest makes them much easier to remove from the tin without breaking. Run a thin knife or offset spatula around the edges of each cup if needed, then gently pop them out. Serve warm or store them in the refrigerator for grab-and-go breakfasts throughout the week.
