Ingredients

• 1/2 cup heavy cream or unsweetened unsweetened almond milk (for lighter option)
• 1 cup shredded cheddar or Monterey Jack (for dairy-free option see substitutions)
• 6 slices bacon, cooked and chopped (or 1 cup cooked sausage crumbles)
• 1/2 cup diced bell pepper (red or green)
• 1 cup baby spinach, roughly chopped
• 1/4 cup finely diced red onion or green onion (optional)
• 1/2 tsp salt, 1/4 tsp black pepper, 1/4 tsp smoked paprika (optional)
• 2 tbsp chopped fresh parsley or chives (optional)

Step-by-step instructions

1. Preheat oven to 375°F (190°C). Grease a 12-cup muffin tin or line with silicone liners.
2. Cook bacon or sausage until crisp and chop. Sauté bell pepper and onion in the bacon fat (or a teaspoon of oil) until softened, about 3–4 minutes. Add spinach for the last minute until wilted; drain any excess liquid and let cool slightly.
3. In a large bowl, whisk eggs with heavy cream (or almond milk), salt, pepper, and smoked paprika until frothy.
4. Stir in shredded cheese, cooked meat, and cooled vegetables. Divide the mixture evenly among the 12 muffin cups (fill about 3/4 full).
5. Bake 18–22 minutes until set and lightly golden on top. A toothpick in the center should come out clean. Let cool in the tin 5 minutes, then transfer to a wire rack.
6. Cool completely before storing (helps prevent condensation and sogginess). For serving reheat instructions, see Storage and meal prep below.

Tips for best results

• Room-temperature eggs mix more uniformly and produce fluffier muffins.
• Don’t overfill cups — eggs rise slightly but can spill if filled to the brim.
• Drain cooked vegetables well to avoid watery muffins.
• To check doneness without overbaking, remove when the center springs back and a toothpick is mostly clean.
• Use silicone liners for easy removal and cleanup. For more storage containers and organization ideas check Keto Storage & Organization.

Substitutions and swaps

• Dairy-free: Omit cheese and stir 2–3 tbsp nutritional yeast for a savory flavor or use a keto-friendly dairy-free shredded cheese alternative. Use unsweetened almond or canned coconut milk instead of heavy cream.
• Vegetarian: Replace meat with chopped mushrooms, sun-dried tomatoes, or additional spinach and increase cheese (or use dairy-free cheese if avoiding dairy).
• Lower fat: Use egg whites for part of the eggs (e.g., 6 whole eggs + 6 egg whites) and unsweetened almond milk.
• Flavor swaps: Add taco seasoning, fresh herbs, or 1/4 cup crumbled feta for Mediterranean style.

Serving ideas

• Serve hot with half an avocado and a sprinkle of fresh herbs for added fats and texture.
• Pair with a low-carb side like cucumber slices or a small mixed greens salad.
• Bring with a portable coffee or creamer for a complete morning. Browse Coffee & Beverage options or try a collagen creamer such as Collagen Coffee Creamer (20 servings) to complement your meal.
• For snack-style portions, pair one muffin with a handful of keto-friendly nuts or cheese from the Keto Snacks selection.

Storage and meal prep

• Refrigerator: Store cooled muffins in an airtight container for up to 5 days. Layer with parchment to prevent sticking.
• Freezer: Flash-freeze on a tray, then transfer to a freezer-safe bag or container. Freeze up to 3 months. Label with date.
• Reheating: From fridge — microwave 2 muffins 30–45 seconds (check and add more time if needed); from frozen — thaw overnight in fridge or microwave 60–90 seconds. For best texture, reheat in a 325°F oven for 8–10 minutes or in an air fryer at 320°F for 4–6 minutes until warmed through.
• For organized batch prep and containers, consider meal prep tools from our Meal Prep collection and storage ideas in Keto Storage & Organization.
