Recipe Ingredients
Here are the ingredients you’ll need to make this delicious and nutritious Oven Baked Vegetable Frittata:

Ingredient Notes
- Eggs: The breakfast all-star! Packed with protein, healthy fats, and essential nutrients, eggs bind the whole thing together!
- Broad Beans (Fava Beans): For an extra hit of protein, broad beans are nutty and creamy when cooked. Plus, they’re packed with fiber to help keep you full until your next meal. I’m using frozen and thawed broad beans for convenience.
- Fresh Vegetables: I’m adding broccoli, celery, red onion, and red bell peppers. Not only are they packed with vitamins, minerals, and fiber, each brings its own unique flavor to the frittata. Combined, we get little hits of sweetness, bitterness, earthiness, and freshness in each mouthful.
- Parmesan Cheese: A little goes a long way with this bold and flavorful cheese.
- Chives: Add a subtle onion-like flavor and vibrant green color with chives.
- Dijon Mustard: For a tangy kick and depth of flavor.
- Nutmeg: Just a pinch of warmth to balance the richness of eggs and cheese.
- Extra Virgin Olive Oil: Choose high-quality olive oil for a delicate and fruity flavor.
- Sea Salt Flakes and Pepper: Season to enhance the flavors and make them pop!
How to Make an Oven-Baked Vegetable Frittata: Step-By-Step
Here’s how to make an Oven Baked Vegetable Frittata in seven illustrated steps:
- Onions and Celery
Sauté the onions and celery until slightly softened.
- Broccoli and Peppers
Add the broccoli and bell pepper and sauté.
- Add the Lid
Put the lid on the pan so the vegetables soften more quickly.
- Eggs
Meanwhile, while the veg is sautéing, beat the eggs in a medium bowl.
- Flavor the Eggs
Add the chives, Dijon mustard, nutmeg, and most of the parmesan to the beaten eggs. Season with salt and pepper. Beat together well.
- Assemble Vegetable Frittata
Spread the cooked vegetables out in a single layer in a baking dish. Pour in the egg mixture. Add the broad beans and sprinkle with parmesan cheese.
- Bake
Bake frittata for 15-20 minutes until the egg has set and the top is golden brown. Serve and enjoy!

Recipe Substitutions and Additions
The best frittata is loaded with flavors you love and suits your personal dietary needs. Here are a few ideas to experiment with:
- Vegetable Variations: Feel free to experiment with different cooked vegetables, such as spinach, mushrooms, zucchini (courgette), spring onions, green onions, chopped asparagus, peas, and cherry tomatoes. Roasted vegetables also taste amazing in this. My favorites are Roasted Butternut Squash and sweet potatoes.
- Cheese Options: If you’re not a fan of Parmesan cheese, you can substitute it with cheddar cheese, feta, gouda, or goat cheese. Adding cream cheese to the egg mixture is also fab if you’re looking for a beautifully creamy texture.
- Herb Swap: Fresh herbs add so much flavor to this egg dish. Replace chives with basil, parsley, or dill to infuse different herbal notes into the frittata.
- Spice it Nice: Add a pinch of smoked paprika or red pepper flakes for a hint of smokiness and heat.
- Protein Boost: For a heartier meal, consider adding cooked bacon, ham, or shredded chicken.

Recipe Tips
When it comes to making the perfect frittata, here’s how you:
- Prevent the frittata from sticking: Thoroughly grease your baking dish or skillet to prevent the frittata from sticking.
- Achieve a light and fluffy frittata: Whisk the eggs well with the other ingredients to create a light and fluffy texture.
- Sauté veggies to avoid a soggy frittata: During the sautéing process, the heat causes the moisture in the vegetables to evaporate. This helps to remove excess water content, preventing it from making the frittata soggy. The high heat also aids in cooking the vegetables evenly and intensifying their flavors.
- Get a bit of everything in each bite: For even distribution of vegetables, make sure to chop them into uniform sizes before adding them to the frittata.
- Check for doneness: To check if the Vegetable Frittata is cooked through, insert a toothpick into the center, and if it comes out clean, it’s ready.
- Slice the frittata into clean wedges: Allow the frittata to cool for a few minutes before slicing to ensure clean and neat servings.
Storage Instructions
- Storage: Once cooled, store any leftover frittata in an airtight container in the refrigerator for 3-4 days.
- Freezing: To freeze, wrap individual portions in plastic wrap (cling film) or place them in a freezer-safe airtight container for up to 1 month. Thaw frozen frittata overnight in the refrigerator before reheating.
What to Serve with Oven-Baked Vegetable Frittata
Oven Baked Vegetable Frittata is delightful on its own but can be accompanied by a variety of sides to create a complete meal. Here are a few suggestions:
- A side salad with a light vinaigrette.
- Crusty sourdough bread or wholegrain toast for a satisfying crunch.
- Oven Roasted New Potatoes, Colcannon, or sweet potato wedges for a heartier meal.
- Fresh fruit or sliced avocado for a refreshing touch.

Yes! Broad beans and fava beans are two different names for the same type of bean. The terms “broad beans” and “fava beans” are used interchangeably in different regions, with “broad beans” more commonly used in the United Kingdom and other parts of Europe, while “fava beans” is the more common term in the United States.
Nutrition Tips: Health Benefits of Broad Beans
Broad beans (or fava beans) are packed with health benefits. Here are just a few to mention:
- Broad beans are rich in fiber and high in protein: Both fiber and protein are nutrients that promote feelings of fullness, which may result in lower calorie intake, which can lead to weight loss for some people. [1, 2]
- Broad beans are a good source of magnesium and potassium: These two minerals help to relax blood vessels which may help prevent high blood pressure. [3]
- Broad beans may support heart health: Broad beans are rich in soluble fiber, which plays a vital role in reducing LDL cholesterol, commonly known as “bad” cholesterol. The soluble fiber binds to cholesterol in the digestive system, preventing its absorption into the bloodstream and aiding its removal from the body. [4]
It’s important to note that while broad beans offer potential health benefits, they should be eaten as part of a balanced diet and lifestyle. It’s always a good idea to consult with a healthcare professional or a registered dietitian for personalized advice based on your individual health needs.

PRINT PIN RATEEquipment
- Frying Pan (with lid) + Baking Dish, Or an oven-safe skillet. A cast iron skillet is great for this!
- Kitchen Spatula
- Medium Bowl
Ingredients
- 1 tablespoon extra virgin olive oil
- 1 red onion, finely sliced
- 2 ribs celery, finely diced
- 3 cups (270 g) broccoli florets
- 1 red bell pepper, finely sliced
- 10 large eggs
- ½ cup grated Parmesan cheese, divided
- 1 tablespoon fresh chives, finely chopped
- 2 teaspoons Dijon mustard
- ¼ teaspoon nutmeg
- large pinch sea salt flakes, Not too much, as the Parmesan is salty.
- pinch black pepper
- 1 cup (170 g) broad beans (fava beans), Frozen, fresh or canned. Drain or thaw in a sieve and then dry with a paper towel to remove excess water.
Instructions
- Prepare: Gather your equipment and prep your ingredients. Preheat the oven to 400ºF/200ºC/gas 6. Grease the oven dish with a little of the olive oil.
- Sauté Vegetables: Sauté the onions and celery in olive oil over a medium-high heat until slightly softened ~ about 5 minutes. Add the broccoli and red bell pepper and sauté for 2-3 minutes to give them a little color. Now, turn the heat down to medium-low, and add the lid on the pan so the vegetables soften quickly ~ about 5 minutes. Stir regularly to stop the vegetables from sticking and burning. The broccoli and peppers should have softened, but you want them to retain some bite as they will continue to cook in the oven. Tip: You can use an ovenproof skillet instead of a frying pan + baking dish if you'd like.
- Egg Mixture: Meanwhile, beat the eggs in a medium bowl. Add most of the Parmesan cheese (reserving 2 tablespoons for the top), the chives, Dijon mustard, and nutmeg to the beaten eggs. Season with salt and pepper. Beat together well.
- Assemble the Frittata: Spread the sautéd vegetables evenly across the bottom of the greased baking dish. Pour the beaten egg mixture over the vegetables. Add the broad beans (so they feature on top) and sprinkle with the remaining Parmesan cheese.
- Bake: Transfer the frittata to the preheated oven and bake for 15-20 minutes until the egg has set and the top is golden brown. Serve and enjoy!
