How To Make an Omelette in the Slow Cooker

Are you ready to make the best veggie omelet without all the work? Let’s do it!

  1. First, lightly grease the inside of the slow cooker/crock pot with cooking spray; set aside.
  2. Then, in a large mixing bowl combine eggs, milk, salt, pepper, garlic powder and chili powder; using a whisk, beat the mixture until mixed and thoroughly combined.
  3. Next, add the broccoli florets, peppers, onions and garlic to the slow cooker; stir in the egg-mixture. By the way, you can also fry the broccoli, peppers, onions, and garlic for few minutes, or until just softened, before adding them to the slow cooker. 
  4. Cover and cook on HIGH for 2 hours. Start checking at 1 hour 30 minutes. Omelette is done when eggs are set.
  5. Next, sprinkle with cheese and cover; let stand 2 to 3 minutes or until cheese is melted. 
  6. Cut the omelette and serve.

How to Store Slow Cooker Veggie Omelette

As with all food that gets stored in the refrigerator or freezer, leftovers from your slow cooker need to be cooled on the countertop to about room temperature before placing into the fridge or freezer for storage.

  • Fridge: Your leftover veggie omelette can be stored the in the fridge in an airtight container for 4 days.
  • Freezer: You can also freeze it. Just, let it cool down completely before putting it in an airtight container. You can store it in the freezer for up to 3 months.
  • Reheat: Reheating the veggie omelette is super easy. Simply bring it to room temperature on your counter, and then heat on your stove top on low. It should only take about 10 minutes to heat through. Do not reheat the veggie omelette in the slow cooker.

NOTE: Also, do not put a refrigerated slow cooker insert into the heating base while it’s still cold; the ceramic could crack and food is at risk of not reaching proper food safety temperature.

Omelette or Omelet?

  • Both spellings can be used. An omelet or omelette is a type of egg dish, often served at breakfast or brunch. Neither spelling is wrong, but there are some guidelines for when to use which. Omelet is the standard spelling in American English. The British spelling, omelette, is actually the modern French spelling.

What Can You put in an Omelette?

Some classic omelette fillings include:

  • Diced ham
  • Crisp bacon
  • mushrooms
  • Bell peppers
  • Tomatoes
  • Caramelized onions
  • Fresh herbs or dried herbs
  • Leftovers from last night’s dinner. 😊

What is a French Omelette?

  • A true French omelette, or omelet as we Americans call it, is just eggs and butter, no filling. The egg is folded for a soft, tender texture.

What is an American Omelet?

  • An American omelet has a speckled golden crust from the pan, and the surface is uneven with craters. The round omelet is then folded in half and served. Often, the fillings like meat and vegetables are cooked into the eggs rather than added afterward.

What is the difference between an Omelette and a Frittata?

  • A frittata is cooked in an oven while an omelet is usually cooked quickly over higher heat on the stove. Whereas omelets are served hot straight from the stove, frittatas are often served at room temperature, making them perfect to make ahead for brunches or larger groups.
