Keto Egg Muffins

These baked egg muffins layer cheddar, crumbled bacon, and sautéed vegetables in a butter-greased 12-cup muffin tin. This is an untested editorial proposal; it is not kitchen-tested.

Recipe status: This fixed editorial formula is not kitchen-tested. The pictures are conceptual illustrations, not photographs of a cooked result. Finished yield, preparation time, texture, storage quality, and nutrition have not been measured or calculated.

Food safety first: For this meat-containing egg dish, check the center of muffins in several areas of the pan with a food thermometer and continue baking until each checked center reaches 165°F (74°C). Refrigerate uneaten muffins in a shallow container within 2 hours of cooking, or 1 hour above 90°F (32°C). See egg with meat leftovers.

Ingredients​

Illustration of eggs, cream, cheddar, bacon, peppers, onion, spinach and seasonings for proposed egg muffins
Illustrated ingredients for the proposed fixed formula; use the measured amounts in the list below.
  • Raw whole egg contents, 600 g weighed after cracking (roughly 12 large eggs; weigh the edible contents)
  • Heavy cream, 120 g (about 1/2 cup)
  • Shredded sharp cheddar cheese, 113 g (about 1 cup), divided
  • Bacon, 170 g raw (about 6 slices), cooked and crumbled
  • Red bell pepper, diced, 75 g (about 1/2 cup)
  • Yellow onion, diced, 40 g (about 1/4 cup)
  • Fresh baby spinach, chopped, 60 g (about 2 cups)
  • Fine sea salt, 3 g (about 1/2 tsp)
  • Black pepper, 0.5 g (about 1/4 tsp)
  • Garlic powder, 0.75 g (about 1/4 tsp)
  • Butter, 14 g (about 1 tbsp), for greasing the muffin tin

Equipment​

  • 12-cup muffin tin
  • skillet
  • large mixing bowl
  • whisk
  • instant-read food thermometer
  • cutting board and knife
  • measuring cups and spoons
  • shallow storage container for the refrigerator

Method​

  1. Preheat the oven to 350°F (175°C) and grease a standard 12-cup muffin tin with most of the measured butter, reserving some in case another batch is needed.
  2. Cook the bacon in a skillet over medium heat, checking for doneness starting around 6 to 8 minutes, until browned throughout; drain on paper towels, then crumble once cool enough to handle.
  3. In the same skillet, cook the diced red bell pepper and yellow onion, checking starting around 3 to 4 minutes, until softened, then add the spinach and cook briefly, checking until just wilted; remove from heat.
  4. In a large bowl, whisk the raw whole egg contents, heavy cream, sea salt, black pepper, and garlic powder until fully combined.
  5. Distribute the crumbled bacon, cooked vegetables, and about three-quarters of the cheddar cheese across the muffin cups, dividing the fillings as evenly as practical.
  6. Pour egg mixture over the fillings without filling any cup more than about three-quarters full, then top with the remaining cheddar. If mixture remains, use the reserved butter to grease cups for another batch rather than overfilling.
  7. Bake, beginning to check for doneness starting around 20 to 22 minutes, using an instant-read food thermometer inserted into the center of muffins in more than one area of the pan; continue baking until every checked center reads at least 165°F (74°C), since this is a meat-containing egg dish.
  8. Remove from the oven and let the muffins rest in the tin for 5 minutes, then run a knife around the edges to loosen each one.
  9. Place any uneaten muffins in a shallow container and refrigerate promptly, within 2 hours of removing the pan from the oven, or within 1 hour if the surrounding temperature is above 90°F (32°C).

Practical notes​

  • Check the center of muffins in more than one location, since fillings and oven hot spots can vary the temperature reached across the pan.
  • A food thermometer reading of 165°F (74°C) is the way to confirm the safe endpoint for this meat-containing egg dish; a set appearance alone is not a safety measurement.
  • A 12-cup muffin tin is the starting equipment, but this formula has not been tested for pan fit or a finished count; work in batches if mixture remains.
  • Refrigerate uneaten muffins in a shallow container promptly within 2 hours of baking (or within 1 hour above 90°F/32°C), and reheat leftovers to 165°F (74°C) if served warm later.

Contains egg and dairy (heavy cream, cheddar cheese) and pork (bacon); this formula does not include tree nuts or fish.

The ingredient choices follow a lower-carbohydrate style, but no nutrient calculation or individual keto-fit verdict has been approved for this formula.
