What Makes This Recipe So Good

• Low-carb and high-protein: Eggs, bacon, and feta bring serious staying power without the carb load.
• Meal prep friendly: Make a batch on Sunday and reheat throughout the week.
• Flavor-packed: Salty bacon and tangy feta play perfectly with tender spinach.
• Simple ingredients: Nothing fancy—just pantry and fridge staples you likely already have.
• Customizable: Swap fillings based on what’s in your fridge or your taste.

What You’ll Need

• 8 large eggs
• 6 slices bacon, cooked and chopped
• 1 cup fresh spinach, chopped (or 3/4 cup thawed frozen spinach, squeezed dry)
• 1/2 cup crumbled feta cheese
• 1/4 cup heavy cream (optional but helps with a softer texture)
• 2 tablespoons chopped green onion (optional)
• 1/4 teaspoon garlic powder
• 1/4 teaspoon onion powder
• Salt and black pepper, to taste
• 1 tablespoon olive oil or butter (for sautéing spinach, if using fresh)
• Nonstick cooking spray or extra butter for greasing the muffin tin

Instructions

1. Preheat the oven. Set your oven to 350°F (175°C). Grease a 12-cup muffin tin well with cooking spray or butter.
2. Cook the bacon. Pan-fry or bake the bacon until crisp.

   Drain on paper towels and chop into small pieces. You can save a little bacon fat for sautéing the spinach if you like.

3. Prepare the spinach. If using fresh, sauté it in a teaspoon of oil or bacon fat over medium heat until wilted, 1–2 minutes. Let it cool slightly.

   If using frozen, thaw and squeeze out as much water as possible.

4. Mix the egg base. In a large bowl, whisk together the eggs, heavy cream, garlic powder, onion powder, a pinch of salt, and a few grinds of black pepper until smooth.
5. Add the fillings. Stir in chopped spinach, crumbled feta, bacon, and green onion if using. Mix until evenly distributed.
6. Fill the muffin cups. Divide the mixture evenly among the 12 cups. Aim for about 3/4 full; they’ll puff as they bake and then settle.
7. Bake. Place the tin in the center of the oven and bake for 16–20 minutes, or until the centers are just set and no longer jiggly.

   A toothpick should come out mostly clean.

8. Cool slightly. Let the egg cups rest in the pan for 5 minutes. Run a thin knife around the edges to loosen, then lift them out.
9. Serve or store. Enjoy warm, or cool completely for meal prep.

How to Store

• Refrigerate: Store in an airtight container for up to 4 days. Reheat in the microwave for 20–30 seconds per cup or in a 300°F oven for 8–10 minutes.
• Freeze: Wrap each egg cup tightly in plastic or foil, then place in a freezer bag.

  Freeze up to 2 months.

• Reheat from frozen: Thaw overnight in the fridge, then warm in the microwave for 30–60 seconds or in a 325°F oven for 12–15 minutes.
• Meal prep tip: Place parchment in the container layers to prevent sticking and sogginess.

Why This is Good for You

• Balanced keto macros: Eggs and bacon supply protein and fat, while carbs stay low, helping you feel full and steady.
• Nutrient-dense: Spinach adds vitamin K, folate, and iron; eggs bring choline and B vitamins; feta contributes calcium.
• Steady energy: Protein and fat digest more slowly than refined carbs, supporting appetite control and focus.
• Gluten-free and grain-free: Naturally suitable for many dietary needs without special ingredients.

Pitfalls to Watch Out For

• Not greasing the pan well: These can stick. Use a generous coating or silicone muffin cups for easy release.
• Watery spinach: Too much moisture leads to soggy cups. Squeeze frozen spinach thoroughly or cook down fresh spinach and drain.
• Overbaking: They’ll turn rubbery if baked too long.

  Pull them when the centers are just set.

• Salting too soon: Feta and bacon are salty. Season lightly at first, then adjust after tasting the mixture.
• Overfilling: Leave some room in each cup. Overfilled cups spill and bake unevenly.

Variations You Can Try

• Mediterranean: Add chopped sun-dried tomatoes (oil-packed, drained) and a pinch of dried oregano.
• Spicy: Mix in red pepper flakes or a little diced jalapeño.

  Top with a dash of hot sauce when serving.

• Mushroom & Herb: Sauté finely chopped mushrooms until browned and dry, then add fresh parsley or dill.
• Ham & Gruyère: Swap bacon for chopped ham and feta for shredded Gruyère.
• Dairy-free: Skip the feta and cream. Add an extra egg and a tablespoon of olive oil for richness.
• Extra veggies: Bell peppers or zucchini work well if finely diced and sautéed to remove moisture.

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 20–25 minutes, or until set.

Slice into squares after cooling for a few minutes.

How many egg cups make a serving?

For most people, 2 egg cups feel like a solid breakfast, especially with a side like avocado or a small salad. Adjust based on your hunger and goals.

Can I use another cheese instead of feta?

Absolutely. Goat cheese, shredded cheddar, or Monterey Jack all work well.

Feta’s tang is unique, but other cheeses melt nicely and taste great, too.

What if I don’t eat pork?

Use turkey bacon, chicken sausage, or skip the meat entirely and add extra veggies. If omitting meat, consider a pinch more salt or a dash of smoked paprika for depth.

Why did my egg cups collapse after baking?

That’s normal. They puff in the oven and deflate as steam escapes.

If they seem too flat, you may have overmixed or baked a bit too long, but they’ll still taste great.

Can I make these in advance for a brunch crowd?

Yes. Bake them the day before, refrigerate, and reheat on a sheet pan in a 300°F oven for 10 minutes. They’ll taste fresh and save you stress on the day.

How low-carb are these egg cups?

Exact carbs depend on your ingredients, but typically each cup has about 1–2 grams of net carbs, mainly from spinach and dairy.

Check your labels to be sure.

Do I need the heavy cream?

No, but it helps with a softer, custardy texture. If you skip it, the cups will be slightly firmer, which some people prefer for meal prep.
