🍳 Ingredients for this keto vegetable frittata recipe

  • 2 tablespoon olive oil
  • 1 ½ cups mushrooms, sliced
  • 1 cup raw bell peppers, cut into thin 1-inch (2.5cm) strips
  • 1 cup zucchini, cut into quarter moons
  • 8 large eggs
  • ¼ cup heavy cream
  • ¾ teaspoon sea salt
  • ¼ teaspoon black pepper
  • ⅔ cup cheddar cheese, shredded

Ingredient substitutions

  • Olive oil: You can substitute it with coconut or avocado oil. But you may notice a slight coconut flavor in the dish when you use coconut oil.
  • Mushrooms: Substitute mushrooms with baby spinach or kale. Cook the fresh spinach or kale until it has wilted and any excess moisture evaporates before adding the egg mixture.
  • Bell peppers: You can replace bell peppers with broccoli. Chop broccoli into small or bite size pieces and add it to the skillet along with the other vegetables.
  • Zucchini: You can use yellow squash as it has a similar texture and flavor to zucchini.
  • Heavy cream: You can use unsweetened coconut cream instead of heavy cream, as coconut cream is thicker and richer.
  • Cheddar cheese: You can replace it with mozzarella or goat cheese.

Additional ingredients

  • Avocado: Dice one avocado and add it to the egg mixture. Also, you can use it as a garnish on top of the finished dish.
  • Tomatoes: You could add diced or cherry tomatoes, as they are low in carbs and high in fiber. If fresh ones are not available, you can also use sun-dried tomatoes.
  • Feta cheese: Add feta cheese for some tangy flavor.
  • Bacon: For those who want some meat, add 4 bacon pieces or crumbled bacon for a smoky flavor and extra protein.
  • Green onions: Mix this with the eggs for a mild onion flavor.

Cooking tools required

To make this Keto Vegetable Frittata Recipe, you'll need the following tools:

  • Oven
  • 10 inch Cast iron skillet
  • Whisk
  • Cutting board
  • Knife

Tools substitute options

  • Spatula: If you don't have a spatula, use a spoon.

Chef's pro tip

Nailing the perfect vegetable frittata requires some finesse - the trick is to avoid overcooking the eggs. As soon as the center is just a bit wobbly, take that skillet off the heat, and stick to the prescribed baking time to prevent any culinary missteps. This guarantees a frittata that's creamy, moist, and cooked to perfection. Additionally, resist the urge to cover it immediately after it comes out of the oven; trapping the steam could turn your scrumptious frittata into a mushy mess.

What to serve keto vegetable frittata recipe?

  • Keto salad: Pair it with a simple side salad of mixed greens, tomatoes, and cucumbers for a light and refreshing meal.
  • Roasted vegetables: Brussels sprouts with bacon make a delicious and nutritious side dish to this keto egg recipe.
  • Condiments: You can spice up the game by serving it with your favorite salsa, hot pepper sauce, or our favorite creamy jalapeno sauce on the side.
  • Guacamole: You can make homemade guacamole using avocados, lime juice, cilantro, diced tomatoes, and spices. This will be a flavorful dip.

How to make it healthier

We have created a healthy frittata recipe that uses an oven-baked method. To have a healthier and more delightful dish, you can make the following tweaks:

  • Use less cheese or opt for a lower-fat cheese such as feta or ricotta.
  • Consider adding more nutrient-dense ingredients such as spinach, kale, or broccoli.
  • Limit the salt you use or substitute it with herbs and spices to add flavor.
  • If you want to make it a dairy-free frittata, you can use vegan options for heavy cream and cheese.

Time-saving tips

  • Use frozen vegetables instead of fresh ones. Just make sure to thaw them before using and pat them dry to remove any excess moisture.
  • Use a food processor to chop your veggies but do not over-process them, or they may become too small and mushy.
  • Use an immersion blender to mix the egg mixture quickly instead of whisking it by hand.

What can I prepare ahead of time?

  • Wash and chop the vegetables ahead of time, and store them in airtight containers in the fridge until ready to use.
  • You can whisk the eggs, coconut cream, salt, and pepper ahead of time and store them in the fridge until ready to use.
  • Buy shredded cheese ahead of time and store it in the fridge until ready to use.

Storage and reheating instructions

You can slice it up into individual portions and store it in the fridge for an easy and convenient breakfast, lunch, or dinner option. You can store the leftovers in an airtight container in the refrigerator for up to 3-4 days.

For reheating cooked leftovers, you can use a microwave, oven, and stove.

  • Microwave: Place the leftovers on a microwave-safe plate, cover the plate with a microwave-safe cover or paper towel, and microwave for 30 seconds to 1 minute or until it is heated.
  • Oven: Preheat the oven to 350°F (180°C), place the leftovers on an oven-safe dish, cover it with foil, and bake for 10-15 minutes.
  • Stovetop: Cut a slice of baked omelet and place it in a nonstick skillet over medium heat. Cook for 2-3 minutes on each side or until it is heated.

When reheating, reheat the leftovers to an internal temperature of 165°F (74°C) to avoid overcooking, as it can cause them to become dry and rubbery.
