Egg muffins are a make-ahead breakfast of beaten eggs baked in a muffin tin with cheese, vegetables, and often meat. They are naturally high in protein and low in carbohydrates, which makes them a popular choice for meal prep. This recipe gives you a basic, versatile base that you can customize, plus the nutrition facts for one standard muffin.
Ingredients
- 12 large eggs
- 1/4 cup (60 ml) milk (any kind, or water)
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 cup (120 g) shredded cheddar cheese
- 1 cup (150 g) diced bell pepper (any color)
- 1/2 cup (80 g) diced onion
- 1 cup (30 g) fresh spinach, roughly chopped
- Nonstick cooking spray or oil for the muffin tin
Instructions
- Preheat your oven to 350°F (175°C). Generously grease a 12-cup muffin tin with cooking spray or oil.
- In a large bowl, whisk the eggs, milk, salt, and pepper until completely combined and slightly frothy.
- Stir in the shredded cheese, bell pepper, onion, and spinach until evenly distributed.
- Pour the egg mixture evenly into the prepared muffin cups, filling each about 3/4 full. Use a spoon to distribute the vegetables and cheese evenly if needed.
- Bake for 18–20 minutes, until the muffins are puffed and set in the center. A knife inserted into the middle should come out clean. The internal temperature should reach 160°F (71°C), the USDA FSIS safe minimum for egg dishes, if you check with a food thermometer.
- Let the muffins cool in the pan for 5 minutes, then run a knife around the edges to loosen them. Carefully remove and serve warm, or let cool completely for storage.
Tips
- Don’t overbake: Eggs continue to cook after you pull them from the oven. Take them out when they are just set – they should still look slightly moist on top. Overbaking makes them rubbery and dry.
- Use a silicone muffin pan: If you have one, silicone pans release egg muffins effortlessly without greasing. If using metal, a generous coat of cooking spray is essential to prevent sticking.
- Customize your add-ins: Almost anything works: cooked sausage, bacon, mushrooms, zucchini, or feta. Just make sure meat is fully cooked before adding, and drain any excess fat or liquid so the muffins don’t become soggy.
- Make them dairy-free: Use unsweetened almond milk or just water instead of milk, and skip the cheese or use a dairy-free shred. The texture will be slightly less fluffy but still delicious.
Serving Suggestions
Egg muffins are great on their own for a quick breakfast. For a heartier meal, serve them with a side of whole-grain toast, fresh fruit, or a simple green salad. They also work well as a protein-packed snack any time of day.
Variations
Meat lover’s: Add 1/2 cup (75 g) of cooked, crumbled bacon or sausage (drained). Veggie-packed: Swap the bell pepper and onion for chopped mushrooms, zucchini, or broccoli – just sauté them first to remove excess moisture. Southwest: Add 1/4 cup (40 g) of corn, a diced jalapeño, and a pinch of cumin. Herb and feta: Use crumbled feta instead of cheddar and add 2 tbsp fresh dill or chives.
Storage and Reheating
Store cooled egg muffins in an airtight container in the refrigerator for up to 4 days. To freeze, place them in a single layer on a baking sheet, freeze until solid, then transfer to a freezer bag – they will keep for up to 3 months. Reheat refrigerated muffins in the microwave for 30–45 seconds, or in a 350°F (175°C) oven for 5–7 minutes. From frozen, microwave for 1–2 minutes or bake at 350°F (175°C) for 10–12 minutes, until heated through to 165°F (74°C).
Frequently Asked Questions
How many calories are in one egg muffin? This recipe makes 12 muffins. One plain muffin (without meat) has approximately 110 calories, 8 g protein, 8 g fat, and 2 g carbohydrates. The exact numbers vary based on the cheese and vegetables you use.
Are egg muffins keto-friendly? Yes, they are naturally low in carbs – about 2 g per muffin. If you add high-carb ingredients like potatoes or corn, the count will go up, so stick to low-carb veggies and cheese.
Can I use egg whites instead of whole eggs? Yes, you can substitute 8 egg whites for 4 of the whole eggs, or use all egg whites (about 1.5 cups / 360 ml) for a lower-fat, lower-calorie version. The texture will be slightly less rich.
Why are my egg muffins sticking to the pan? Even with greasing, they can stick. Let them cool for 5 minutes before removing – this helps them release. Using a silicone pan or paper liners also solves the problem.
Can I make these ahead of time? Absolutely. They are designed for meal prep. Cook them, cool completely, and refrigerate or freeze as described above. They reheat beautifully.
What is the best way to reheat frozen egg muffins? For best texture, thaw overnight in the fridge, then microwave for 30–45 seconds. If reheating from frozen, microwave for 1–2 minutes, checking that they are hot all the way through.
