 Equipment Needed

• Standard 9-inch pie dish
• Mixing bowls (1 large, 1 medium)
• Whisk or fork
• Skillet for caramelizing onions
• Knife & cutting board
• Measuring cups and spoons
• Oven mitts and cooling rack

 Ingredients

• 1 pre-made pie crust (or homemade if preferred)
• 6–8 slices bacon, cooked and crumbled
• 1 large onion, thinly sliced
• 2–3 ripe tomatoes, sliced ¼-inch thick
• 1 cup shredded cheddar cheese (or cheese blend)
• 2 large eggs
• 1 cup milk or half-and-half
• Salt and black pepper, to taste
• Optional: 2 tbsp chopped fresh herbs (parsley, basil, or thyme)

 Instructions

Step 1 – Prep Your Pie Dish

Preheat your oven to 375°F (190°C). Press the pie crust into a standard 9-inch pie dish and crimp the edges if desired.

Step 2 – Caramelize the Onion

In a skillet over medium heat, cook the onion slices until golden and soft, about 10–15 minutes. Set aside to cool slightly.

Step 3 – Layer the Ingredients

Sprinkle half the crumbled bacon over the crust. Add a layer of tomato slices. Top with half the caramelized onions, then half the cheese.

Step 4 – Mix the Custard

In a medium bowl, whisk together the eggs, milk (or half-and-half), salt, pepper, and herbs if using.

Step 5 – Assemble and Pour

Pour the egg mixture evenly over the layered ingredients. Top with the remaining bacon, onions, and cheese.

Step 6 – Bake

Bake for 35–45 minutes or until the center is fully set and the top is golden brown.

Step 7 – Rest and Serve

Let the pie rest for 10–15 minutes before slicing. This helps it firm up and makes slicing easier.

 Tips & Variations

• No pre-made crust? Use puff pastry or make your own flaky dough.
• Add heat: Mix in a pinch of red pepper flakes or diced jalapeño.
• Make it vegetarian: Skip the bacon and add sautéed mushrooms or spinach.
• Dairy-free? Use almond milk and dairy-free cheese for a lighter version.

 Perfect Pairings

Serve with a simple arugula salad, roasted potatoes, or a fresh fruit bowl. It also pairs beautifully with a cold glass of iced tea or a mimosa for brunch lovers.
