I love muffin tin omelets and have been making them for years. They are often featured in many diet plans because you can make them in advance and freeze them for a quick, easy, and healthy breakfast or snack. I’ve even had them for a light dinner on nights when I’ve been too tired to cook.

Best of all, these little muffin omelets are delicious. You can add ingredients from the refrigerator and feel good about using leftovers in new ways. I eat them hot or cold, often grabbing one or two out of the fridge as a midday protein boost. Pair them with a piece of fruit or a handful of berries, and you will be ready to take on whatever’s ahead for you.

Are Muffin Tin Omelets Healthy?

Muffin tin omelets are a healthy and convenient way to start your day. They are packed with protein, nutritious vegetables, and calcium-rich cheese while staying low in carbs, sugar, and calories. Eggs used to have a bad reputation because of their cholesterol content, but research now shows that, for most people, dietary cholesterol from eggs does not significantly raise blood cholesterol or heart disease risk.

That said, these little omelets are moderate in fat and sodium—with most of the fat coming from eggs, sausage, and cheese—though the sodium content is still lower than many traditional breakfast options. If you’re watching your cholesterol or sodium intake, be sure to enjoy these in moderation or consider using reduced-sodium cheese. These omelets are also gluten-free, making them a delicious option for people who avoid gluten-containing breakfast foods.

My favorite recipes are those that allow me to tailor the dish to whatever leftovers I have in my fridge. And an omelet is one of the best ways to use leftovers. From pot roast to roasted vegetables, anything you find in your refrigerator is fair game for these little omelets.

You can play with interesting or familiar flavor combinations for your signature creation. Go south-of-the-border with onions, peppers, salsa, and cotija cheese. Make Italian-style omelets with sausage, mozzarella, tomatoes, and Italian seasoning. Go Greek with feta cheese, leftover lamb, kalamata olives, and spinach. The combinations are endless—limited only by your palate and imagination.

FAQs & Tips

How Do I Store Leftovers?

Let the muffins cool to room temperature before refrigerating in an airtight container or zipper bag for up to 5 days. Once cold, you can freeze them in plastic zipper bags for up to 1 month. I like to use freezer-safe zipper bags or silicone bags because you can squeeze out the extra air in the bag, which keeps the egg muffins fresher. Reheat frozen muffins in the microwave, oven, or air fryer. You don’t need to defrost them first.

Can I Make These Without Dairy?

Yes! You don’t need dairy to make delicious omelets in muffin tins! I’ve made veggie-packed variations of this recipe that were so full of flavor and texture that I never missed the cheese—so just leave it out, if you like. You can also get excellent results with your favorite plant-based, non-dairy cheese. Also, don’t forget to swap the milk for your favorite plant-based alternative.

How To Keep Omelets From Sticking To The Tin

I often like to make little omelets in silicone muffin pans or cups, rather than in metal cupcake pans. They work better to prevent sticking than traditional tins. If a metal muffin tin is all you have, use a little cooking oil spray to keep the eggs from sticking to the sides. There’s no need to spray silicone trays or cups with oil.
