  • 12 oz. bacon, chopped
  • 1 medium Farmer’s Promise red onion, thinly sliced
  • 2 tsp. fresh thyme leaves, chopped
  • 12 large eggs
  • 1 ½ tsp. Kosher salt, course
  • ½ tsp. black pepper
  • 1 tbsp. extra virgin olive oil
  • 4 oz. shredded Swiss cheese


  • Preheat oven to 350-degrees with a rack in the center position.
  • In a large, high-sided non-stick skillet or sauté pan, add the chopped bacon. Place cold pan and bacon over medium heat to render bacon. Once crispy, remove the bacon from the pan and set aside. Drain excess bacon fat until about 2 tablespoons are left. Return to heat.
  • Add the onions to the hot pan and cook until they just begin to brown, about 8 minutes. While the onions are cooking, whisk together the eggs, salt, pepper and oil in a large mixing bowl until uniform. Just before the onions are finished, add the thyme and cook until soft, about 2 minutes.
  • Add the onion and thyme mixture to the eggs, then return the pan to the heat. Add the reserved bacon and Swiss cheese to the eggs and whisk everything together, then pour back into the pan. Immediately transfer the eggs to the preheated oven and bake for about 20minutes, or until the center of the frittata is firm.
  • When finished, use a heat proof glove to remove the frittata from the oven and let rest for about 5 minutes before serving.

Recipe Tips

Frittata is most easily served right out of the pan. Simply slice with a rubber spatula or pie server, being careful not to damage the pan.
If you want to turn the frittata out onto a cutting board, be sure to run a rubber spatula along the edges and gently under the center to release first.
Gruyere, Cheddar, gouda, and Manchego are all great cheese substitutes for this frittata.
Using a sweet bacon will cause sugar to stick to the pan and interfere with the frittata releasing after cooking.
