For 4 servings
- prep
Preheat the oven and prep the muffin tin.
1.Preheat oven to 375°F (190°C).2.Grease 8 cups of a 12-cup muffin tin with butter, coating bottoms and sides well.TIPGrease generously so the muffins release cleanly. Silicone muffin liners work too. - mix
Whisk the egg base.
In a large mixing bowl, crack all 8 eggs. Add the milk, salt, black pepper, and garlic powder. Whisk vigorously until the eggs are uniform in color and slightly frothy — about 30 seconds.
- mix
Fold in the vegetables and cheese.
Add the diced bell pepper, chopped spinach, chopped onion, and shredded cheddar to the egg mixture. Stir gently with a spatula until everything is evenly distributed — the greens should be speckled throughout.
TIPDon't overmix here or the veggies will sink to the bottom. A few gentle folds is enough. - assemble
Fill the muffin cups.
Using a ladle or measuring cup, divide the egg mixture evenly among the 8 greased muffin cups. Fill each about three-quarters full, leaving a little room for the muffins to puff. Sprinkle any remaining cheese on top if you set some aside.
- bake · ~20 min
Bake until golden and set.
Place the muffin tin on the middle rack and bake for 18-22 minutes. The egg muffins are done when the tops are puffed, lightly golden, and the center springs back when pressed gently. A toothpick inserted in the center should come out clean.
TIPWatch closely after 18 minutes. Overbaking makes them rubbery — pull them the moment they're set. - rest · ~5 min
Cool briefly before removing.
Let the egg muffins rest in the tin for 3-5 minutes. Run a butter knife around the edges to loosen, then lift each muffin out onto a wire rack or plate.
TIPThey'll deflate slightly as they cool — that's normal. The texture stays soft and custardy. - serve
Serve warm or cool for meal prep.
Enjoy warm right from the oven, or cool completely before packing into airtight containers for the fridge or freezer. They reheat beautifully in the microwave for 30-45 seconds.

Meat Lover's
Add 1/2 cup cooked crumbled sausage or diced ham for a heartier, protein-packed breakfast. Sauté the meat before mixing it in to render fat and deepen the flavor.
Low Carb / KetoLow-Carb / Keto
Skip the onion (which adds a few carbs) and replace bell pepper with sautéed mushrooms. Use full-fat milk or cream to keep the fat high without increasing carbs.
Dairy FreeDairy-Free
Substitute the cheddar with 1/3 cup dairy-free shredded cheese (like almond-based cheddar style) and replace the milk with unsweetened almond milk. The results are still rich and fluffy.
Spicy SouthwesternSpicy Southwestern
Add 1/4 cup canned black beans (rinsed), 2 tablespoons diced jalapeño, and 1/4 teaspoon cumin. Top with a pinch of chili powder for a Tex-Mex twist that works great with cilantro on top.
