Quick Skillet Frittata
1 tablespoon (15 ml) butter
½ cup diced onion
½ cup sliced button mushrooms
2 cups (480 ml) shredded purple sweet potatoes
½ pound kielbasa sausage, thinly sliced
12 large eggs, whisked
- In a medium-size nonstick skillet, heat the butter and sauté the onions and mushrooms for 3 minutes. Remove to a plate and set aside.
- Place the shredded sweet potatoes on a paper plate and microwave on high for 2 minutes to soften.
- Cook the sausage in the skillet used for the onions over medium heat until browned, about 5 minutes. Remove to a plate and set aside.
- Cover the entire bottom of the skillet with the shredded sweet potatoes and then spoon the reserved onions and mushrooms on top.
- Pour the whisked eggs over the vegetables in the skillet and then place the sausage slices on top like you would a pizza.
- Cover the skillet and cook the frittata for 10 to 15 minutes, or until the eggs have firmed up.
- Slice the frittata like a pie and serve at once.
VARIATION: If you don’t have access to purple sweet potatoes, any kind of sweet potato would be fine.

This quick skillet frittata builds a crust of shredded purple sweet potatoes on the bottom of the pan, layers in sauteed onion, mushrooms, and browned kielbasa, then sets it all with twelve whisked eggs. Covered and cooked entirely on the stovetop, it slices like a pie. No oven required.
Pro Tips
- Microwave the shredded sweet potatoes for 2 minutes first to soften them. Raw shreds will not cook through under the eggs.
- Cover the entire bottom of the skillet with the sweet potato shreds. That layer is the crust, and it crisps against the buttered pan.
- Arrange the kielbasa slices on top like pizza toppings. They brown nicely and look great when the frittata is sliced.
- Cook the frittata covered for 10-15 minutes until the eggs have firmed up. Resist lifting the lid - the steam is what sets the top.
- No purple sweet potatoes at the store? Any kind of sweet potato works here.
Frequently Asked Questions
Is this frittata paleo?
Check the kielbasa label, since sausages vary. With clean sausage it is eggs, sweet potato, onion, mushrooms, and butter (or ghee).
Can I make the frittata ahead of time?
Yes - it is excellent cold or at room temperature. Refrigerate leftovers for up to 4 days and slice it straight from the fridge.
Can I use regular sweet potatoes instead of purple?
Absolutely - any kind of sweet potato works. The purple ones simply make the slices more dramatic.
Why did my frittata stick to the pan?
A nonstick skillet and enough butter are essential here. The sweet potato crust needs direct contact with the fat to release cleanly.
