Description
A delicious and healthy frittata packed with cheddar cheese, mushrooms, and kale, perfect for breakfast or brunch.
Ingredients
- 1.5 Tablespoons olive oil or avocado oil
- 1/2 cup diced onions
- 8 ounces mushrooms, thinly sliced
- 1 cup chopped kale
- 2 cloves garlic, minced
- 1/21/2 teaspoon salt, divided
- black pepper, to taste
- 6 large eggs
- 1/3 cup milk of choice
- 1/2 cup grated cheddar cheese, optional
- 1/21/2 teaspoon salt
Instructions
- Preheat & Prepare Oven: Start by preheating your oven to 375 degrees F. This ensures the frittata sets evenly and has a nice golden brown top.
- Sauté Vegetables in Skillet: Heat the olive oil in a large skillet over medium heat. Add the diced onions, followed by the chopped mushrooms and kale. Sauté for about 5 to 7 minutes until the vegetables are tender and fragrant. Be careful not to overcook them, as that could lead to overly crispy results.
- Whisk Eggs in Bowl: In a large bowl, whisk the eggs until they become frothy and bubbly. This is key to a light texture in your frittata. If the eggs are not well mixed, it could cause uneven cooking.
- Add Cheese & Mix: If using, fold in the grated cheddar cheese into the egg mixture gently. This will help it melt throughout without overmixing.
- Combine Egg & Veggies: Pour the egg mixture over the sautéed vegetables in the skillet. Stir gently to ensure all ingredients are combined without breaking down the vegetables.
- Bake Until Set: Place the skillet in the preheated oven and bake for about 35 minutes, or until the frittata puffs up and is golden brown. Make sure to check that the center is set and not soggy by gently shaking the skillet.
- Cool & Slice Frittata: Once baked, allow the frittata to rest for a few minutes before slicing. This resting time helps in cutting neater slices. If you slice too soon, it may fall apart.
Notes
- Storage Tips: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350 degrees F or in the microwave before serving.
- Expert Tips: Cut the hard stems from the kale before using it. If your frittata sticks to the pan, ensure to grease the pie plate thoroughly. For finely chopped vegetables, consider using a food processor for quicker preparation.
- Reheating Instructions: Reheat in the oven at 350 degrees F for about 10 minutes or in the microwave until warmed through.
- Serving Suggestions: Serve with fresh fruit on the side, or pair with a mixed green salad for added crunch. Enjoy with whole grain toast for a heartier meal.
- Recipe Variations: You can add cooked bacon or sausage for a heartier option. Try incorporating bell peppers or zucchini for variety, or make mini frittatas in muffin tins for easy portion control.
- Ingredient Notes: You can substitute kale with fresh spinach if preferred. Omit cheese or use your favorite plant-based cheese for a dairy-free option. Use any preferred milk, including unsweetened almond milk, for a non-dairy choice.
