Ingredients

• 10 large eggs
• 1/3 cup milk (dairy or unsweetened almond milk)
• 8 oz lean chicken or turkey sausage, casings removed (or pre-cooked crumbles)
• 1 cup baby spinach, chopped
• 1 cup bell peppers, finely diced (mix of red, yellow, green)
• 1/2 small red onion, finely diced
• 1/2 cup shredded cheese (cheddar, Monterey Jack, or feta crumbles; optional)
• 2 cloves garlic, minced
• 1/2 tsp kosher salt, plus more to taste
• 1/4 tsp black pepper
• 1/2 tsp smoked paprika (optional but recommended)
• 1–2 tbsp olive oil or avocado oil
• Nonstick spray or silicone muffin liners

Cooking Instructions

1. Prep the pan: Preheat oven to 350°F (175°C).

   Spray a 12-cup muffin tin generously with nonstick spray or use silicone liners. Don’t skimp—eggs stick like gossip.

2. Cook the sausage: Heat 1 tbsp oil in a skillet over medium. Add sausage and cook, breaking into small crumbles, until browned and cooked through, 5–7 minutes.

   Drain excess fat if needed.

3. Sauté the veggies: In the same pan, add onion and peppers with a pinch of salt. Cook 3–4 minutes until softened. Stir in garlic for 30 seconds.

   Add spinach and cook just until wilted, 1–2 minutes. Remove from heat.

4. Whisk the eggs: In a large bowl, whisk eggs, milk, salt, pepper, and smoked paprika until well combined and slightly frothy.
5. Build the cups: Divide sausage and veggie mixture evenly among the 12 muffin wells. Sprinkle cheese if using.
6. Pour and fill: Pour the egg mixture over fillings, filling each cup about 3/4 full.

   Give the pan a gentle shake to settle.

7. Bake: Bake 16–20 minutes, until set in the center and lightly puffed. They may dome and then deflate—totally normal, not a baking fail.
8. Cool and release: Let rest 5 minutes in the pan, then run a thin spatula around edges to release. Move to a rack to cool completely if storing.
9. Serve: Enjoy hot or at room temp.

   Add hot sauce, salsa, or a dollop of Greek yogurt if you’re fancy.

How to Store

• Fridge: Store in an airtight container up to 4 days. Reheat in microwave 25–40 seconds. If you overshoot, they’ll get rubbery—don’t do that.
• Freezer: Wrap individually or place in a freezer bag with air pressed out.

  Freeze up to 2 months.

• Reheat from frozen: Microwave 60–90 seconds at 50–70% power, or thaw overnight and reheat 25–40 seconds.
• Meal prep tip: Store with a dry paper towel in the container to absorb moisture and keep texture on point.

Why This is Good for You

• Protein for satiety and energy: Eggs and lean sausage deliver a solid protein hit that helps control hunger and keeps you focused.
• Micronutrient dense: Spinach brings iron and folate; peppers add vitamin C; eggs deliver choline for brain health. That’s a lot of win for a tiny muffin.
• Lower carb, balanced fat: Great for blood sugar control and those who prefer fewer morning carbs. Add a piece of fruit or toast if you want a carb assist.
• Portion control built in: Each muffin is a consistent serving, so tracking is simple and overeating is less likely—unless you eat six.

  Respect.

Avoid These Mistakes

• Skipping the sauté: Raw onions and peppers release water and make soggy muffins. Cook the veg first, always.
• Overfilling the cups: Eggs puff, then set. Fill 3/4 full max or you’ll get muffin lava.
• Under-seasoning: Eggs need salt.

  Taste your veggie mixture and season your egg base. Bland is avoidable.

• Using full-fat, greasy sausage: Too much fat = greasy bottoms. Lean sausage keeps things clean and macro-friendly.
• Forgetting to grease well: Nonstick spray or silicone liners are your best friends.

  A stuck muffin is a broken heart.

Variations You Can Try

• Mediterranean: Swap sausage for chopped turkey, add sun-dried tomatoes, olives, spinach, and feta. Finish with oregano.
• Southwest: Use turkey chorizo, add black beans and corn, cheddar, and top with salsa or avocado. Cumin and chili powder for extra pop.
• Veggie-loaded: Mushrooms, zucchini, and broccoli (pre-sautéed).

  Sprinkle with goat cheese for tang.

• Dairy-free: Skip cheese and use unsweetened almond milk. Add nutritional yeast for a cheesy vibe, IMO.
• Breakfast BLT-ish: Turkey bacon, tomatoes, spinach, chives. A touch of smoked paprika seals the deal.
• Herb garden: Fresh dill, parsley, and chives with a light Swiss cheese.

  Bright, fresh, and brunchy.

FAQ

Can I use whole eggs and egg whites together?

Yes. Use 6 whole eggs + 1 cup liquid egg whites for a leaner version with similar volume. Add an extra pinch of salt since whites mute flavor.

How do I prevent the muffins from deflating?

A slight collapse is normal.

To minimize it, avoid overbaking, let them rest 5 minutes in the pan, and don’t slam the tray on the counter like you’re in a cooking show.

Do I need a silicone muffin pan?

No, but silicone makes release easier. If using metal, spray generously and loosen edges with a thin spatula while still slightly warm.

What’s the best cheese for these?

Cheddar melts well and adds richness. Feta brings tang and less melt.

Pepper Jack gives heat. Use 1/2 cup total to avoid greasy muffins.

Can I make this as a full frittata instead?

Absolutely. Pour everything into a greased 9-inch pie dish or 8×8 pan and bake at 350°F for 22–28 minutes, until center is just set.

Are these good cold?

Yes.

They’re tasty at room temp or cold, especially with a little hot sauce or pesto. Great for grab-and-go breakfasts or post-workout snacks.

How many should I eat for breakfast?

For most adults, 2 muffins with fruit or toast is a balanced start. Adjust based on your hunger and goals—FYI, they’re easy to track.

Can I add potatoes or hash browns?

You can, but pre-cook them until crisp and dry.

Otherwise they’ll water down the eggs and wreck the texture.

Why are my muffins watery on the bottom?

Likely under-sautéed veggies or high-fat sausage. Cook off moisture, drain fat, and don’t add watery add-ins like raw tomatoes without pre-cooking.

What’s the calorie and protein estimate?

Varies by sausage and cheese. Roughly 110–150 calories and 9–12g protein per muffin with lean sausage and a light sprinkle of cheese.
