Mason Jar Omelettes Recipe


Mason Jar Omelettes began on a quest for wholesome, fuss-free breakfast options. Tired of the usual grab-and-go meals, I longed for something that could combine the nutritional punch of a well rounded meal with the convenience my busy mornings demanded. And thus, the Mason Jar Omelette was born a recipe that I have since tweaked and perfected to what I believe is its finest iteration.

Crafted with the finest ingredients, this recipe is more than just eggs in a jar. It’s an invitation to explore the endless possibilities of breakfast, encouraging you to mix and match ingredients to suit your taste. From the sharpness of aged cheddar to the freshness of spinach and the robust flavors of cherry tomatoes and bell peppers, each ingredient adds its unique note to this symphony of flavors.

Recipe Ingredients

  • Eggs: 4 large ones, whisked to airy perfection. They form the foundation of our omelette, a fluffy cloud to cradle our medley of additions.
  • Fresh Veggies: 1/2 cup, diced with care. Think bell peppers in a rainbow of colors, tender spinach, or sweet cherry tomatoes, bringing freshness and a burst of color to your dish.
  • Cheese: 1/4 cup, shredded. Whether it’s the melt-in-your-mouth goodness of mozzarella, the sharp bite of cheddar, or the creamy tang of feta, cheese adds a rich depth to our omelette.
  • Cooked Protein: 1/4 cup, crumbled or diced. Be it the savory sweetness of ham, the crispiness of bacon, or the hearty bite of sausage, this is where we infuse our dish with umami and satisfaction.
  • Milk: 2 tablespoons, the secret to an omelette that’s as fluffy as a cloud. It’s all about adding that touch of creaminess and luxury to the texture.

How to Make This Mason Jar Omelettes Recipe

  • Gather Your Ingredients: Begin by assembling all the ingredients listed. This ensures a smooth cooking process, allowing you to focus on the art of combining flavors.
  • Dice Your Veggies and Protein: Uniformity is key here. Dice your chosen veggies and cooked protein into small, bite-sized pieces. This not only ensures they cook evenly but also makes every spoonful a perfect balance of flavors and textures.
  • Whisk the Eggs: In a bowl, whisk the eggs until they are fully blended and airy. This is the secret to a fluffy omelette. Add the milk at this stage and whisk again to incorporate. Season with salt and pepper to taste.
  • Layering the Ingredients: In a clean, dry mason jar, start by layering half of your diced veggies. Follow this with a layer of half the cooked protein, and then sprinkle half the cheese over the top. Repeat these layers until your ingredients are all snugly fitted into the jar.
  • Pouring the Egg Mixture: Gently pour the whisked egg and milk mixture over the layered ingredients in the jar. A gentle tap on the counter will help remove any air bubbles and ensure the egg mixture settles well among the layers.
  • Closing the Jar: Screw the lid on tightly. This will prevent any spillage and ensure even cooking.
  • Preheat Your Oven: Set your oven to 350°F (175°C). While it heats, place your mason jar (or jars, if you’re making multiple servings) on a baking tray.
  • Bake: Place the baking tray in the oven and bake for about 20-25 minutes. The exact time may vary depending on your oven, so it’s wise to start checking at the 20-minute mark. You’re aiming for an omelette that’s set, fluffy, and lightly golden on top.
  • Resting: Remove the jars carefully from the oven (they will be hot!) and let them rest for a few minutes. This resting period allows the omelette to settle and makes it easier to unscrew the lid.

Serving Instructions

To serve, simply unscrew the lid of the mason jar and enjoy your omelette straight from the jar, or gently slide it onto a plate. The Mason Jar Omelette is best enjoyed hot, with a side of toast or a fresh salad for a complete meal. Remember, the jar will be hot, so handle with care.

Storage and Freezing Instructions

  • Storage: If you have leftovers or prefer to prepare your omelette ahead of time, allow the jar to cool completely before sealing with the lid. Store it in the refrigerator for up to 2 days. To reheat, remove the lid and microwave the jar for 1-2 minutes, or until heated through.
  • Freezing: Freezing is not recommended for this recipe. Eggs and fresh veggies may change texture upon thawing, affecting the delightful experience of your Mason Jar Omelette.
  • Creating a Mason Jar Omelette is more than just cooking; it’s about embracing creativity, nourishment, and the joy of sharing a meal. Whether you’re a seasoned chef or a culinary novice, this dish is a testament to the beauty of simple ingredients coming together to create something extraordinary. Enjoy the process, and relish the delicious outcome.
