Everything You Need for Complete Breakfast Muffins

- 2 1/2 cups (12 1/2oz/355g) all-purpose flour (spooned and leveled for accuracy)
- 1/2 tablespoon baking powder
- 1 teaspoon salt
- 1/2 teaspoon onion powder
- 1 cup (8floz/225ml) milk (whole or 2% works best)
- 1 large egg
- 1/2 cup (4oz/115g) sour cream (Greek yogurt can be substituted)
- 4 tablespoons (2oz/57g) butter, melted and cooled
- 4 green onions, thinly sliced
- 10 strips bacon, cooked until crisp then chopped
- 2 cups (8oz/225g) cheddar cheese, shredded (sharp or mild, your choice)
- 12 hard-boiled eggs, peeled (make ahead for convenience)
Step-by-Step Instructions for Perfect Breakfast Muffins
- Prepare the dry ingredients: In a large bowl, combine the flour, baking powder, salt, and onion powder. Mix well.
- Mix the wet ingredients: In a separate jug or bowl, whisk together the milk, egg, sour cream, and melted butter until smooth and evenly combined.
- Combine wet and dry ingredients: Pour the wet mixture into the dry ingredients. Use a spatula to gently mix until a thick batter forms. Avoid overmixing.
- Add mix-ins: Fold in the bacon, green onions, and shredded cheddar cheese until evenly distributed.
- Preheat the oven: Set your oven to 375°F (190°C) and generously butter a 12-well muffin tin.
- Assemble the muffins: Using two spoons, drop a heaped tablespoon of batter into the bottom of each muffin well. Place one hard-boiled egg in the center of each, pressing down slightly to ensure it touches the batter.
- Cover the eggs: Add another heaped tablespoon of batter on top of each egg. Use the spoons to push the batter down the sides, fully encasing the egg.
- Bake: Place the muffin tin in the preheated oven and bake for 25 minutes, or until the muffins are firm and golden brown on top.
- Cool and serve: Allow the muffins to cool slightly in the tin before removing. Enjoy warm or store in an airtight container in the refrigerator for up to 3 days.
Perfect Pairings: Serving Suggestions
These Complete Breakfast Muffins are hearty enough to stand alone, but they pair wonderfully with a fresh fruit salad or a dollop of avocado salsa for a refreshing contrast. For a full breakfast spread, serve alongside a smoothie or a cup of coffee. Pro tip: Add a drizzle of hot sauce or a smear of cream cheese for an extra flavor boost!
Storage and Reheating Made Easy
Store your muffins in an airtight container in the refrigerator for up to 3 days. To reheat, simply pop them in the microwave for 20-30 seconds or warm them in a 350°F (175°C) oven for 5-7 minutes. For best results, wrap them in foil to retain moisture while reheating in the oven.
Recipe Variations to Mix It Up
Feel free to customize these muffins to suit your taste! Swap the cheddar for pepper jack cheese for a spicy kick, or use turkey bacon for a lighter option. Vegetarian? Skip the bacon and add sautéed spinach or diced bell peppers. Experimenting with different ingredients can make this recipe your own!
Time-Saving Tips for Busy Mornings
Prep your ingredients the night before to save time. Cook and chop the bacon, shred the cheese, and boil the eggs ahead of time. You can even mix the dry ingredients and store them in a sealed container. When you’re ready to bake, simply combine the wet and dry ingredients and assemble the muffins in minutes!
Equipment Guidance for Success
A sturdy 12-well muffin tin is essential for this recipe. For easy removal, consider using silicone muffin liners or generously greasing the tin with butter. A large mixing bowl and a reliable spatula will make combining the batter a breeze. Don’t forget a sharp knife for slicing the green onions and chopping the bacon!
