Ingredients
- 1 piece Bell Pepper (finely chopped)
- 3 stalks Green Onions (chopped)
- 1 medium Sweet Potato (grated, about 1 cup)
- 1 cup Cheddar Cheese (grated)
- 5 large Eggs (room temperature)
- 0.5 cup Milk (whole or 2%)
- 1 teaspoon Dijon Mustard
- 0.5 teaspoon Salt
- 0.25 teaspoon Black Pepper (freshly ground)
- 1 pinch Nutmeg (freshly grated)
- 0.25 cup All-Purpose Flour
Instructions
Prepare toppings
Finely chop the bell pepper and green onions. Grate the sweet potato and cheddar cheese. If using frozen vegetables, thaw and pat dry thoroughly. Spread the chopped vegetables evenly in the bottom of the 8‑inch cast‑iron skillet, then sprinkle the grated cheese over them.
Time: PT10M
Blend the egg mixture
Crack the five eggs into the blender. Add 1 cup grated cheese, ½ cup milk, 1 tsp Dijon mustard, ½ tsp salt, ¼ tsp black pepper, a pinch of freshly grated nutmeg, and ¼ cup flour. Blend on medium speed until the mixture is completely smooth with no lumps.
Time: PT5M
Combine filling with toppings
Pour the blended egg mixture over the layered vegetables and cheese in the skillet. Gently stir with a spatula to ensure the veggies are evenly coated but not broken up.
Time: PT2M
Bake the quiche
Place the skillet in a pre‑heated oven at 350°F (175°C) and bake for about 35 minutes, or until the top is golden and the center is set (a gentle shake should not cause the center to jiggle).
Time: PT35M
Temperature: 350°F
Cool before slicing
Remove the skillet from the oven and let the quiche rest for 20 minutes. This allows the filling to set so it slices cleanly. Then cut into wedges and serve.
Time: PT20M

Troubleshooting
Bottom is soggy.
Make sure vegetables are patted dry before layering and increase oven temperature to 375°F for the first 10 minutes.
Quiche cracks on top.
Avoid over‑mixing the batter and bake at a moderate temperature; covering with foil halfway prevents excessive browning.
Slices fall apart.
Allow the quiche to rest the full 20 minutes; this lets the custard set firmly.
Storage
Refrigerator: Cover tightly and store for up to 4 days.
Freezer: Wrap each slice in plastic wrap and foil; freeze up to 2 months.
Room temperature: Can sit at room temperature for up to 2 hours; keep covered.
Make-Ahead Tips
- Chop and grate all vegetables and cheese a day ahead; store in airtight containers.
- The quiche can be baked fully, cooled, and reheated in the oven or microwave.
