- Cooking spray or olive oil: Either option prevents sticking and adds a touch of richness to the veggies without weighing them down.

How to Make Healthy Breakfast Sandwich
Step 1: Cook the Veggies
Start by heating a skillet over medium-low heat, then add either a bit of cooking spray or olive oil—whichever you prefer! Toss in the diced onions and let them sauté for a few minutes until they’re soft and fragrant. Once they’re perfectly translucent, add the spinach, stirring gently until it’s wilted and deep green. Take the pan off the heat and set the veggies aside to cool. This early step loads your eggs with savory flavor and a bit of moisture, which keeps the sandwich filling light but never dry.
Step 2: Prep the Egg Mixture
Crack the eggs and egg whites into a mixing bowl and get whisking! A quick 30-second whisk will make the eggs light and fluffy—just what you want. Next, pour in the milk, sprinkle in the salt and black pepper, and whisk again to combine. Fold in the shredded cheddar, cherry tomatoes, and your cooled spinach-onion mixture. A gentle stir is all you need to bring this Healthy Breakfast Sandwich filling together. The veggies and cheese will be perfectly distributed, ensuring every bite is full of flavor.
Step 3: Bake the Eggs
Preheat your oven to 375 degrees F. Take a 9×13 baking pan or a sturdy baking sheet and give it a generous coating of cooking spray—no one wants stuck-on eggs! Pour the egg mixture evenly into the pan, then slide it into the oven. Bake for 25 to 30 minutes, or until the center is set and the top looks slightly golden. Let this egg “slab” cool a bit so it’s easier to cut. Baking the eggs means you can perfectly portion out the filling for each sandwich, making this recipe an ideal candidate for meal-prep or a make-ahead brunch.
Step 4: Build the Breakfast Sandwiches
While your eggs are baking, slice your English muffins and spread them out on a second baking sheet. Pop them in the oven during the last 10 minutes of egg baking time, and after 7 minutes, add a slice of cheddar cheese to each muffin bottom. Let them finish warming for just a few minutes more to get perfectly gooey cheese and lightly golden muffins. Once cooled, use a round object (like a mason jar lid or cookie cutter) to cut the baked eggs into circles. Layer the eggs onto one side of the muffin, top with the cheese-melted side, and press gently. One Healthy Breakfast Sandwich down, five to go!
How to Serve Healthy Breakfast Sandwich

Garnishes
A little garnish can go a long way with this Healthy Breakfast Sandwich. Try a sprinkle of fresh chives or parsley for color and flavor, or a dash of hot sauce for a zesty kick. If you want a little crunch, add some thinly sliced radishes or pickled onions on the side. These finishing touches make the breakfast sandwich feel restaurant-worthy without much fuss.
Side Dishes
Pairing your Healthy Breakfast Sandwich with just the right side dish can turn breakfast into a true morning feast. Fresh fruit salad adds a juicy, refreshing contrast, while crispy roasted potatoes or sweet potato hash provide comfort and extra energy for the day ahead. For lighter mornings, simple cucumber and tomato slices tossed in a vinaigrette complement the sandwich’s savory profile.
Creative Ways to Present
Transform your Healthy Breakfast Sandwich into a fun breakfast platter by slicing each sandwich in half and arranging them on a large board with berries, yogurt cups, and small bowls of salsa or avocado mash. This is a guaranteed crowd-pleaser at brunch gatherings! Or take it on the go: wrap a sandwich in parchment for a portable, mess-free breakfast that keeps things tidy for your busy commute.
Make Ahead and Storage
Storing Leftovers
If you have any leftover Healthy Breakfast Sandwiches (which is rare, trust me!), simply wrap each one in foil or parchment and pop them in the fridge. They’ll keep well for up to three days, making your mornings a breeze. For best results, keep the sandwich components separate—the egg portion and the muffins—then assemble just before eating.
Freezing
This sandwich freezes beautifully, so you can make a double batch and save time all week! Allow each sandwich to cool completely, then wrap it tightly in plastic wrap and place in a freezer-safe bag or container. They’ll last up to two months. When you’re ready, just thaw overnight or in the microwave and reheat as needed.
Reheating
To revive your Healthy Breakfast Sandwich, remove any wrapping, place it on a plate, and microwave for 1 to 2 minutes, or until heated through. For an even crispier muffin, you can reheat the sandwich in a toaster oven or regular oven at 350 degrees F for about 10 minutes. Quick, easy, and still delicious!
FAQs
Can I make this Healthy Breakfast Sandwich dairy-free?
Absolutely! Swap the milk for your favorite non-dairy alternative like almond or oat milk, and use dairy-free cheese shreds and slices. You’ll still get a creamy, cheesy texture without missing a beat.
What other veggies can I add to the sandwich?
Feel free to customize! Mushrooms, bell peppers, or even kale work wonderfully in place of or alongside the spinach and tomatoes. This recipe is super flexible, so go with what’s fresh and in season.
How can I make this sandwich gluten-free?
Just use gluten-free English muffins, which are widely available in most grocery stores. The egg filling is naturally gluten-free, so a simple bread swap makes the entire recipe safe for gluten sensitivities.
Can I add meat to this Healthy Breakfast Sandwich?
Of course! Crispy turkey bacon or lean ham tucked under the cheese would be delicious, but rest assured, this vegetarian version is so hearty and satisfying on its own, you won’t miss the meat if you skip it.
Is this recipe good for meal prep?
It’s made for it! Prepare all the steps in advance, wrap each sandwich, and keep them chilled or frozen. Reheat whenever you need a quick, nourishing breakfast that’s ready in minutes—meal prep gold!

Ingredients
For Cooking Veggies
- Cooking spray or 2 teaspoons olive oil
- 1/2 white onion, diced
- 5 oz fresh spinach
For the Egg Mixture
- 6 large eggs
- 4 egg whites
- 1/4 cup milk
- 1/2 teaspoon kosher salt
- 1/4 teaspoon ground black pepper
Add-ins & Sandwich Components
- 1/4 cup shredded cheddar cheese
- 1 cup sliced cherry tomatoes
- 6 English muffins (sourdough or whole wheat preferred)
- 6 cheddar cheese slices
Instructions
- Cook the Veggies: Heat a skillet over medium-low heat and spray with cooking spray or add olive oil. Once hot, add the diced onions and cook for 2-3 minutes until translucent. Stir in the spinach and cook until wilted, about 2 minutes. Remove the mixture from the skillet and let it cool.
- Prep the Egg Mixture: In a medium-sized mixing bowl, crack the eggs and add the egg whites, whisking well for about 30 seconds until fully combined. Whisk in the milk, salt, and pepper. Add the shredded cheddar cheese, sliced cherry tomatoes, and the cooled spinach-onion mixture, then gently mix everything together until evenly distributed.
- Bake the Eggs: Preheat your oven to 375°F (190°C) and spray a 9×13-inch baking pan or baking sheet thoroughly with cooking spray to prevent sticking. Pour the egg mixture into the prepared pan, spreading it out evenly. Bake for 25-30 minutes, until the eggs are set and firm in the middle. Remove from the oven and let cool for a few minutes.
- Toast the English Muffins: While the eggs are baking, slice the English muffins in half and arrange them on a baking sheet. Place them in the oven (alongside the eggs, if space allows) and toast for 10 minutes. After 7 minutes, add a slice of cheddar cheese to the bottom half of each muffin and return to the oven to finish toasting and melt the cheese, about 3 minutes. Remove from oven.
- Assemble the Breakfast Sandwiches: Use a round glass, mason jar lid, or round cookie cutter to portion the baked eggs into pieces that fit your muffins. If you don’t have a cutter, simply use a knife to cut rectangles or squares, lifting with a spatula. Place a cut egg round onto the muffin half without cheese, then cap it with the half topped with melted cheddar. Repeat with the remaining sandwiches and serve fresh, or wrap for later.
Notes
- Sandwiches can be wrapped individually and refrigerated for up to 4 days, or frozen for up to 1 month.
- Reheat in the microwave (wrapped in a paper towel) for 60-90 seconds, or until heated through.
- Swap in your favorite veggies like bell peppers or mushrooms for variety.
- Try whole wheat or multigrain muffins for extra fiber.
- For a spicy kick, add hot sauce or a sprinkle of chili flakes before serving.
