Tired of grabbing a sugary granola bar while running out the door? I get it. Mornings are crazy, and breakfast often gets pushed to the side.

They are simple to make, packed with good stuff, and ready to grab and go all week. Let’s make your mornings a little easier and a lot more delicious.

- 1/4 cup milk (any kind works)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 cup chopped spinach, packed
- 1 red bell pepper, finely diced
- 1/2 cup diced onion
- 1 cup shredded cheddar cheese
- 1 tablespoon olive oil
Tools You’ll Use
You don’t need any fancy kitchen gadgets for this one. Just the basics will do the job perfectly.

- Large mixing bowl
- Whisk
- Cutting board
- Knife
- Skillet

How to Make Veggie Frittata Cups
Follow these steps exactly, and you’ll have perfect frittata cups every time. Don’t skip pre-cooking the veggies; it’s a game changer.
Step 1: Preheat your oven to 375°F (190°C). Grease a 12-cup muffin tin very well with oil or cooking spray. Sticking is the enemy here.
Step 2: Heat the olive oil in a skillet over medium heat. Add the diced onion and bell pepper. Cook for about 5-7 minutes, until they are soft.
Step 3: Add the chopped spinach to the skillet. Cook for another 1-2 minutes until it has wilted down completely. Remove the skillet from the heat and let the veggies cool slightly.
Step 4: In a large bowl, crack all 12 eggs. Add the milk, salt, and pepper. Whisk everything together until it’s light and a little frothy.
Step 5: Spoon the cooked vegetable mixture evenly into the bottom of the 12 muffin cups.
Step 6: Sprinkle the shredded cheese over the vegetables in each cup.
Step 7: Carefully pour the egg mixture over the veggies and cheese, filling each cup about three-quarters full. Don’t overfill them, or they will spill over in the oven.
Step 8: Bake for 15-20 minutes. You’ll know they’re done when the centers are set and no longer jiggly. A toothpick inserted into the center should come out clean.
Step 9: Let the frittata cups cool in the tin for a few minutes. Then, run a knife around the edges to loosen them and gently lift them out.
Pro Tips
After making thousands of these, I’ve learned a few things. These small details make a big difference.
- Don’t Skip Sautéing: Cooking the onions and peppers first removes extra water. This prevents your frittata cups from becoming soggy and gives them a much better flavor. Raw veggies just don’t taste as good here.
- Grease That Pan Well: I can’t say this enough. Eggs love to stick. Be generous with your oil or cooking spray, getting into every corner of the muffin cups. Silicone muffin pans are also a great option if you have one.
- Avoid Overbaking: Pull the frittatas out of the oven as soon as the center is set. If you overbake them, they can become rubbery and dry. They will continue to cook a little from the residual heat after you take them out.
- Let Them Rest: Give the frittata cups about 5 minutes to cool in the pan before you try to remove them. This helps them set up and makes them much easier to get out in one piece.
Substitutions and Variations
One of the best things about this recipe is how easy it is to change. You can use whatever you have in your fridge.
| Ingredient | Substitution Idea | Notes |
|---|---|---|
| Cheddar Cheese | Feta, Goat, or Swiss | Feta adds a salty flavor. |
| Red Bell Pepper | Mushrooms, Broccoli | Chop broccoli very fine. |
| Spinach | Kale, Arugula | Kale needs a little more cook time. |
| Onion | Scallions, Shallots | Scallions are milder. |
You can also add some protein to make them even more filling. Cooked and crumbled bacon, sausage, or diced ham are great additions. Just add them in with the cheese.
Make-Ahead Tips
These are perfect for meal prep. You can get a head start to make your week even easier.
- Chop Veggies: Dice your onions and peppers ahead of time. Store them in an airtight container in the fridge for up to 3 days.
- Mix and Wait: You can whisk the egg mixture and store it in a sealed container in the fridge for up to 2 days. Just give it a quick whisk before pouring.
Nutrition and Meal Pairing
These little cups are full of protein and veggies. They are a great way to start your day without a lot of carbs or sugar.
| Diet Type | Ingredient Swap |
|---|---|
| Keto | Use heavy cream instead of milk. |
| Dairy-Free | Use unsweetened almond milk and dairy-free cheese. |
| Paleo | Omit the cheese and use a compliant milk. |
They are great on their own, but if you want a more complete meal, here are some ideas.
Pairing Suggestions
| Serve With | Why It Works |
|---|---|
| Fresh Fruit | Adds sweetness and fiber. |
| Sliced Avocado | For healthy fats and creaminess. |
| Toast | A classic breakfast side. |
Leftovers and Storage
Store any leftover frittata cups in an airtight container in the refrigerator. They will stay fresh for up to 4 days.
You can also freeze them. Let them cool completely, then place them on a baking sheet in the freezer for an hour. Once they’re firm, transfer them to a freezer-safe bag. They will last for up to 3 months.
To reheat, you can microwave them for 30-60 seconds or warm them in an oven or toaster oven at 350°F for about 10 minutes. The oven method keeps them from getting rubbery.
Frequently Asked Questions
Q1. Why did my frittata cups turn out watery?
Ans: This usually happens because the vegetables released too much moisture. Make sure you cook your veggies first to get rid of that extra water. Spinach and mushrooms are especially known for this.
Q2. Can I use paper or silicone muffin liners?
Ans: Yes, you can. If you use paper liners, make sure to spray them with cooking spray first, as the eggs can still stick to the paper. Silicone liners work great and usually don’t need any grease.
Q3. My frittatas deflated after I took them out of the oven. Is that normal?
Ans: Yes, it’s completely normal for them to puff up in the oven and then sink a little as they cool. This happens as the steam inside escapes.
Q4. Can I make this in a regular pie dish instead of a muffin tin?
Ans: Absolutely. Just pour the entire mixture into a greased 9-inch pie dish. You’ll need to increase the baking time to about 25-30 minutes, or until the center is fully set.
