Step-by-step instructions
Follow these straightforward steps to assemble and bake your colorful, sliceable sweet potato frittata perfectly.
Step 1: Prepare the pan
Preheat your oven to 375°F and lightly grease a round baking pan. Spread the mashed sweet potato evenly across the bottom to form a solid crust.
Step 2: Add the broccoli
Scatter the fresh broccoli florets evenly over the sweet potato base. Ensure they are distributed well so every slice gets a good amount of greens.
Step 3: Sprinkle the peas
Add the green peas over the broccoli layer. These small pops of green add sweetness and a lovely texture contrast to the final baked dish.
Step 4: Arrange the onion
Place the sliced red onion rings on top of the vegetables. The onion will caramelize slightly during baking, adding a mild, savory flavor to the frittata.
Step 5: Whisk the eggs
Crack the eggs into a bowl and whisk them thoroughly until the yolks and whites are fully combined. Season the mixture lightly with salt and pepper.
Step 6: Pour the egg mixture
Carefully pour the whisked eggs evenly over the arranged vegetables in the pan. The liquid will naturally seep down to bind all the ingredients together as it bakes.
Step 7: Top with cheese
Sprinkle the shredded cheese generously over the top of the unbaked frittata. This final layer will melt and create a delicious, golden-brown crust in the oven.
Step 8: Bake until set
Place the pan in the preheated oven and bake for 30 to 35 minutes. The frittata is ready when the edges are golden and the center is completely firm.
