Vegetable Frittata

Move over boring breakfast options! Frittatas are where it’s at, my friend. Seriously, these babies have become my ultimate go-to when I want to whip up something insanely delicious at home. And guess what? My latest creation, the Oven Baked Vegetable Frittata, has stolen the show and become my absolute favorite. Well, along with my other favorite – the Ground Beef Cheeseburger Frittata. They’re both just so good I can’t decide.

If you’re unfamiliar with frittatas, they’re basically baked eggs and a delightful medley of veggies, herbs, and a sprinkle of cheese. But here’s my favorite thing. Frittatas aren’t limited to breakfast and brunch. Oh no. They’re a great way to get a tasty dinner on the table during those busy weeknights we all know so well!

If you’re looking for more delicious breakfast recipes, I’ve got plenty more for you to choose from. To break your fast with something hearty, a Healthy Full English Breakfast will hit the spot. But if it’s something light and fruity you’re after, my Blueberry Porridge is a winner!

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!

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.

Frequently Asked Questions

What is a frittata?

A frittata is an Italian dish that can be described as a type of unfolded baked or fried omelet (omelette) or a crustless quiche. It is made by whisking together beaten eggs with various ingredients such as vegetables, cheese, herbs, and sometimes meat. The mixture is then poured into a skillet or baking dish and cooked until it sets and becomes firm.

Is Vegetable Frittata healthy?

Yes! If you’re looking for healthy eating recipes, you can add Oven Baked Vegetable Frittata to your list. It’s loaded with delicious and nutritious ingredients. However, as “healthy” means different things to different people, my best advice is to enjoy this frittata as part of a varied and balanced diet. Including a variety of foods in your meals will help keep you feeling satisfied and nourished.

Can I make this frittata ahead of time?

Yes! You can make the frittata ahead of time and reheat it when needed. It’s a great option for meal prep.

Can I use fresh broad beans instead of frozen ones?

Absolutely! If you have fresh broad beans, blanch them in boiling water for a few minutes, then remove the outer skin before adding them to the frittata.

Are broad beans the same as fava beans?

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:

  1. 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]
  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]
  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.

Equipment

  • 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! 

Notes

Storage Instructions: Cool to room temperature, transfer to an airtight container, and refrigerate for 3-4 days.
Freezing Instructions: Cool to room temperature, slice into individual slices, transfer to a freezer-safe airtight container, and freeze for up to 1 month. For best results, defrost thoroughly in the fridge overnight before reheating.
Reheating Instructions: Cover the frittata with tin foil and pop it into a 350°F/180°C/gas mark 4 oven for about 12-15 minutes or until it’s heated through. Alternatively, pop the Vegetable Frittata into the microwave for 3-6 minutes or until piping hot.
