Egg muffins are a simple, protein-packed breakfast made by whisking eggs with milk, cheese, and your choice of add-ins, then baking them in a muffin tin until set. They are perfect for busy mornings because they come together in about 30 minutes and can be made ahead for the week. This recipe is endlessly customizable, so you can use whatever vegetables, meats, or cheeses you have on hand.
Ingredients
- 8 large eggs
- 1/4 cup (60 ml) milk (any kind works)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 cup (50 g) shredded cheddar cheese, divided
- 1/2 cup (75 g) diced bell pepper (any color)
- 1/4 cup (40 g) diced onion
- 1/2 cup (75 g) cooked and crumbled bacon or sausage (optional)
- 1 tablespoon (15 ml) olive oil or butter, for greasing the muffin tin
Instructions
- Preheat your oven to 350°F (175°C). Grease a 12-cup muffin tin with olive oil or butter, or line with silicone muffin liners for easy removal.
- In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined and slightly frothy.
- Stir in the bell pepper, onion, cooked meat (if using), and half of the shredded cheese. Mix until everything is evenly distributed.
- Pour the egg mixture evenly into the prepared muffin cups, filling each about 3/4 full. Sprinkle the remaining cheese on top of each muffin.
- Bake for 18–20 minutes, or until the edges are set and the centers are just firm to the touch. The internal temperature should reach 160°F (71°C) as the safe minimum for egg dishes, per USDA FSIS guidelines.
- Remove from the oven and let cool in the pan for 5 minutes. Run a knife around the edges to loosen, then carefully lift out the muffins. Serve warm.
Tips
- Don’t overbake: Eggs continue to cook as they cool, so pull them out when the centers are just set but still slightly soft. Overbaked muffins become rubbery.
- Use a muffin liner: Silicone liners are the easiest for release, but paper liners work if you spray them with nonstick spray first.
- Drain watery vegetables: If using mushrooms, zucchini, or tomatoes, sauté them first and pat dry to remove excess moisture; otherwise, your muffins may be soggy.
- Customize freely: This recipe is a base—swap in spinach, feta, ham, or potatoes. Just keep the total add-ins to about 1 1/2 cups so the muffins hold together.
Serving Suggestions
Serve egg muffins warm with a side of fresh fruit, toast, or a simple green salad. They also pair well with roasted potatoes or a smoothie for a more filling breakfast. For a brunch spread, arrange them on a platter with yogurt, granola, and fresh orange juice.
Variations
- Vegetarian: Omit the meat and add 1/2 cup (75 g) of chopped spinach or kale (sautéed and squeezed dry) plus 1/4 cup (30 g) of crumbled feta.
- Southwest: Add 1/4 cup (40 g) of drained black beans, 2 tablespoons of chopped cilantro, and a pinch of cumin. Top with a little pepper jack cheese.
- Mediterranean: Use 1/4 cup (40 g) of chopped sun-dried tomatoes, 1/4 cup (30 g) of crumbled feta, and 1 tablespoon of chopped fresh oregano.
- Bacon & Cheddar: The classic—use 4 slices of cooked bacon, crumbled, and sharp cheddar. Add a dash of hot sauce for a kick.
Storage and Reheating
Store leftover egg muffins in an airtight container in the refrigerator for up to 4 days. To freeze, wrap each muffin individually in plastic wrap, then place in a freezer-safe bag for up to 2 months. To reheat, microwave a refrigerated muffin for 30–45 seconds, or a frozen one for 1–2 minutes, until warmed through. You can also reheat them in a toaster oven at 350°F (175°C) for 5–7 minutes for a crispier exterior.
Frequently Asked Questions
Can I make egg muffins without a muffin tin?
Yes, you can use a regular 8×8-inch baking dish and bake for 25–30 minutes, then cut into squares. The cooking time will be slightly longer, so check for doneness at 25 minutes.
Why are my egg muffins sticking to the pan?
Eggs are notorious for sticking. Use a generous amount of butter or oil, or better yet, silicone liners. Make sure to let them cool for 5 minutes before attempting to remove them.
Can I use egg whites instead of whole eggs?
Absolutely. Substitute 8 large eggs with 1 1/2 cups (360 ml) of liquid egg whites. The muffins will be lower in fat and calories, but they may be slightly less fluffy.
How do I know when they are done?
Insert a toothpick into the center of a muffin—it should come out clean, or the center should feel firm when gently pressed. For accuracy, use a food thermometer; the internal temperature should read 160°F (71°C).
Can I add raw meat to the batter?
No, always cook raw meat like bacon, sausage, or ham before adding it to the egg mixture. Raw meat will not cook through properly in the short baking time and poses a food safety risk.
Can I make these dairy-free?
Yes, use unsweetened almond milk or oat milk instead of dairy milk, and skip the cheese or use a dairy-free shredded alternative. The texture will be slightly softer, so consider adding 1 tablespoon of cornstarch to the egg mixture to help them set.
