Cheesy Bacon & Spinach Egg Muffins – Easy, Make-Ahead Breakfast

Egg muffins are the kind of breakfast that make busy mornings feel calm. They’re quick to assemble, easy to customize, and satisfying without being heavy. These Cheesy Bacon & Spinach Egg Muffins are hearty, savory, and full of protein to keep you going.

You can bake a batch on Sunday and enjoy them all week. They reheat beautifully and taste great warm or at room temperature.

What Makes This Special

These egg muffins balance flavor, texture, and nutrition in a way that feels effortless. You get the smoky richness of bacon, the creaminess of cheese, and the freshness of spinach all in one bite.

They’re naturally low in carbs and high in protein, but they don’t taste “diet-y.” You can take them on the go or dress them up for brunch. Best of all, they use everyday ingredients and require minimal prep.

Ingredients

• 8 large eggs
• 6 strips thick-cut bacon, cooked and crumbled
• 1 cup fresh spinach, chopped (lightly packed)
• 1 cup shredded cheese (cheddar, Monterey Jack, or a blend)
• 1/4 cup milk or half-and-half (for a softer, fluffier texture)
• 1/4 teaspoon garlic powder
• 1/4 teaspoon onion powder
• 1/4 teaspoon smoked paprika (optional, but great with bacon)
• Salt and black pepper, to taste
• 1 tablespoon olive oil or butter (for sautéing spinach, if desired)
• Nonstick cooking spray or a little oil for the muffin pan

How to Make It

1. Preheat and prepare the pan. Set your oven to 350°F (175°C). Lightly grease a 12-cup muffin tin with nonstick spray or brush with oil to prevent sticking.
2. Cook the bacon. Pan-fry the bacon over medium heat until crisp.

   Drain on paper towels, then crumble. You can also bake it on a sheet pan at 400°F (205°C) for 15–18 minutes.

3. Wilt the spinach. In a small skillet, add a touch of olive oil or butter. Sauté the chopped spinach for 1–2 minutes until just wilted.

   Remove from heat and let it cool slightly. Pat away excess moisture with a paper towel.

4. Whisk the eggs. In a large bowl, whisk eggs with milk, garlic powder, onion powder, smoked paprika, salt, and pepper until smooth and well combined.
5. Add the fillings. Stir in the crumbled bacon, wilted spinach, and shredded cheese. Reserve a little cheese to sprinkle on top, if you like.
6. Fill the muffin cups. Divide the mixture evenly among the 12 cups, filling each about 3/4 full.

   Top with the reserved cheese for extra meltiness.

7. Bake. Place the tray on the middle rack and bake for 16–20 minutes, until the centers are set and a toothpick comes out clean. The muffins will puff up and slightly dome.
8. Cool and release. Let the muffins cool in the pan for 5 minutes, then run a thin spatula or butter knife around the edges to loosen. Transfer to a wire rack to finish cooling.
9. Serve or store. Enjoy warm, or let them cool completely before refrigerating for meal prep.

Keeping It Fresh

These keep well and hold their texture.

Store in an airtight container in the fridge for up to 4–5 days. To reheat, warm in the microwave for 25–40 seconds per muffin, or in a 300°F (150°C) oven for 8–10 minutes.

For longer storage, freeze in a single layer until solid, then move to a freezer bag. They’ll keep for up to 2 months.

Reheat from frozen in the microwave for about 60–90 seconds, or thaw overnight in the fridge and reheat briefly.

Why This is Good for You

• Protein-packed: Eggs and bacon provide sustained energy and help keep you full.
• Veggie boost: Spinach adds fiber, iron, and vitamins A and K without overpowering the flavor.
• Smarter fats: Cheese and eggs offer satisfying fats that make breakfast feel complete.
• Low carb, high flavor: Great for anyone looking to cut refined carbs without missing out on taste.

Pitfalls to Watch Out For

• Sticking to the pan: Even “nonstick” pans benefit from a good spray or light oiling. Silicone muffin cups are a foolproof option.
• Watery muffins: Squeeze or pat moisture from spinach after wilting. Avoid adding watery vegetables raw.
• Rubbery texture: Don’t overbake.

  Pull them when the centers are just set; they’ll finish gently as they rest.

• Too salty: Bacon and cheese add salt. Taste your egg mixture before adding extra salt, and season lightly.
• Uneven sizes: Use a measuring cup or large scoop to portion the mixture so they bake evenly.

Variations You Can Try

• Mushroom & Swiss: Sauté sliced mushrooms until browned, then pair with Swiss cheese.
• Ham & Broccoli: Swap bacon for diced ham and fold in finely chopped, steamed broccoli.
• Southwest Style: Add diced bell pepper, green onion, pepper jack cheese, and a pinch of cumin.
• Mediterranean: Use feta, chopped sun-dried tomatoes, and a handful of parsley.
• Dairy-Free: Skip the cheese and use a splash of unsweetened almond milk; add extra herbs for flavor.
• Vegetarian: Omit bacon and add caramelized onions or roasted red peppers for richness.
• Extra Greens: Fold in kale (finely chopped and sautéed) or arugula for a peppery kick.

FAQ

Can I make these without a muffin tin?

Yes. Pour the mixture into a greased 8×8-inch baking dish and bake at the same temperature for 22–28 minutes, until set.

Slice into squares for easy portions.

Do I have to cook the spinach first?

It’s best to wilt it quickly so it releases moisture before baking. If you add it raw, chop it very finely and use a bit less to avoid watery muffins.

What’s the best cheese to use?

Cheddar is classic and melts well. Monterey Jack, Colby, Swiss, or a sharp white cheddar all work.

For a bolder flavor, try a mix of cheddar and Parmesan.

How do I keep them from deflating?

Some slight settling is normal. To minimize deflating, avoid overmixing, don’t overbake, and let them rest in the pan for about 5 minutes before removing.

Can I add more vegetables?

Absolutely. Stick to vegetables that sauté well and lose moisture, like mushrooms, onions, or zucchini (grated and squeezed).

Keep total add-ins to about 1 1/2 cups so the eggs still bind.

Are these good for kids?

Yes. The familiar flavors of cheese and bacon are kid-friendly. You can finely chop the spinach so it blends in, and use milder cheese if needed.

What if I don’t eat pork?

Use turkey bacon, chicken sausage, or a vegetarian bacon alternative.

Season a touch more to make up for the lower smokiness.

Can I make them the night before?

Yes. You can bake the muffins, cool, and refrigerate overnight. Reheat in the morning.

Or refrigerate the whisked egg mixture and fillings separately and assemble right before baking.

How many muffins make a serving?

Two muffins are a common serving for adults, especially if you pair them with fruit or toast. For a light snack, one muffin works well.

Can I use egg whites only?

Yes. Use about 2 cups of liquid egg whites and add an extra tablespoon of oil or a splash of half-and-half for tenderness.

Bake time may be slightly shorter, so start checking around 14–15 minutes.
