Ingredients
Method
Preheat and Prep Your Crust
- Preheat your oven to 375°F (190°C). Place your pie crust into a 9-inch pie dish and press it gently against the sides.
- Prick the bottom a few times with a fork to prevent the crust from puffing up.
- Pre-bake the crust for 8 minutes until it is just barely set. You are not looking for color here, just structure.
Sauté the Onion
- While the crust pre-bakes, melt the butter in a small skillet over medium heat.
- Add the diced onion and cook for about 4–5 minutes, stirring occasionally, until soft and just beginning to turn translucent.
Whisk the Egg Filling
- In a large mixing bowl, crack in the eggs and whisk them together with the heavy cream and milk until fully combined and slightly frothy.
- Add the salt, pepper, and nutmeg. Whisk until everything is smooth and cohesive.
Build Your Quiche
- Scatter the cooked bacon or ham and sautéed onion evenly across the bottom of the pre-baked crust.
- Sprinkle the shredded Gruyère over the top in an even layer.
- Slowly pour the egg mixture over everything, pouring gently so the fillings stay in place and the liquid settles evenly to the edges.
Bake Until Just Set
- Carefully transfer the quiche to the oven and bake for 30–35 minutes, until the edges are puffed and golden and the center jiggles just slightly when you nudge the pan.
- Pull it out when a knife inserted 1 inch from the center comes out clean.
- Let it rest for 5–10 minutes before slicing so the filling can settle into clean, beautiful wedges.
Notes
Meal-Prep Tip: Sauté your onions and cook your bacon the night before. Store them covered in the fridge so you can simply assemble and bake the next day. Common mistakes to avoid: skipping the pre-bake (leads to soggy crust), overbaking (causes rubbery texture — pull it when the center still jiggles), overfilling the crust (stop pouring when filling is about ¼ inch below the crust rim), and using cold eggs straight from the fridge (room-temperature eggs blend more smoothly). Storage: Store leftover quiche covered in the refrigerator for up to 4 days. To freeze, wrap individual slices tightly in plastic wrap and foil — they keep well for up to 2 months. Reheat slices in a 325°F oven for 10–15 minutes for the best texture. Avoid the microwave as it tends to make the custard rubbery. Substitution Tips: For dairy-free, use full-fat coconut milk in place of heavy cream and milk. For a kid-friendly version, skip the onion and swap bacon for mild shredded cheddar and diced cooked chicken. For a budget-friendly option, blended cottage cheese can replace half the heavy cream.
