Spinach Egg Bite Recipe Ingredients

• Bacon: Any regular-cut bacon works well; regular cut cooks faster than thick cut. Omit for a vegetarian version or substitute ham or cooked sausage.
• Cheese: Gruyère lends a nutty, savory flavor. You can substitute cheddar, Swiss, Fontina, Comté, or another melting cheese you prefer.
• Spinach: Frozen chopped spinach, thawed and well drained, is convenient. If using fresh spinach, sauté until wilted and squeeze out excess moisture.
• Milk: 2% or whole milk yields a creamier texture; low-fat milk or a milk substitute will also work but may be slightly less rich.

How to Make Spinach Egg Bites

1. Preheat the oven to 350°F. Spray a 12-cup muffin tin with cooking spray.
2. Cook about 4 ounces (4–5 slices) of bacon until crisp. One quick method is to microwave bacon between paper towels, or cook it in a skillet or in the oven. Let cool and chop.
3. Shred about 2 ounces gruyère (roughly ½ cup). Reserve 2 tablespoons to sprinkle on top of the cups.
4. Squeeze as much liquid as possible from 2½ ounces thawed frozen spinach, using a clean towel or your hands.
5. In a large bowl, whisk together 10 large eggs, ½ cup milk, ½ teaspoon kosher salt, and ¼ teaspoon freshly ground black pepper until combined.
6. Fold in the chopped bacon, shredded cheese (reserve the 2 tablespoons), and the squeezed spinach.
7. Pour the mixture into the prepared muffin tin, filling each cup about ¾ full. Distribute solids and liquid evenly among cups. Sprinkle the reserved cheese on top of each.
8. Bake 18–20 minutes, until the egg mixture is just set. Avoid overbaking; the bites will set slightly as they cool.
9. Let the cups cool in the pan until firm enough to remove. Serve warm.

Egg Bite Variations

This recipe is very flexible. Swap the Gruyère for sharp cheddar, pepper jack, feta, or gouda. Instead of bacon, try diced ham, crumbled sausage, or smoked salmon. Add vegetables like sautéed mushrooms, roasted red peppers, sun-dried tomatoes, or diced bell peppers. For a lighter version, replace half the eggs with egg whites and use low-fat milk. Make sure any added vegetables are cooked and patted dry to avoid excess moisture so the bites set properly.

Storing Bacon Egg Bites with Spinach

Store cooled egg bites in an airtight container in the refrigerator for 3–4 days. For longer storage, freeze up to 3 months. To freeze without sticking, arrange cooled egg cups on a sheet tray so they are not touching, freeze until solid, then transfer to a zip-top freezer bag. Alternatively, wrap each bite individually in plastic wrap and then foil. Reheat from frozen in a microwave or oven until heated through.

Frequently Asked Questions

What can I substitute in these egg cups? The recipe is adaptable: omit the bacon for a vegetarian version, or replace the gruyère with other cheeses such as cheddar, gouda, or feta. Spinach can be omitted or swapped for other greens or vegetables. Try ricotta or cottage cheese for a creamier texture.

Why are my egg bites rubbery? Overcooking causes a rubbery texture. Remove the bites as soon as the center is set and the egg custard no longer jiggles; they will finish setting while cooling.

Are these gluten-free? Yes. There is no flour or gluten-containing ingredient in this recipe.

👩‍🍳 Expert Tips

• Cook bacon until very crisp so it crumbles easily and won’t become soggy inside the egg custard.
• Grease the muffin pan well—the egg bites can stick. Use cooking spray, butter, or a light coating of oil.
• Use a ladle to fill muffin cups evenly and avoid spills.
• Prep these on a meal-prep day: they store and reheat well for quick breakfasts throughout the week.
