Easy Ham and Cheese Quiche

Here are all of the ingredients for this quiche recipe including simple substitutions.

• 1 tablespoon unsalted butter – Adds richness and helps soften the onions and garlic. You can use salted butter. Just decrease the salt to ¼ teaspoon.
• ½ cup onion, finely diced – Brings a subtle sweetness. Yellow, white, or even shallots work well.
• 1 garlic clove, finely minced – This gives a little extra depth of flavor. If you’re a garlic lover, feel free to add another clove.
• 4 large eggs – The base of the custard, giving structure to the quiche.
• 1 cup half-and-half or milk – Half-and-half gives a richer texture, but whole or 2% milk also works. Use heavy cream to make it extra decadent.
• ½ teaspoon dried thyme (or 1 teaspoon fresh thyme leaves, finely chopped) – Adds a light, earthy note. Feel free to use oregano or basil for a twist.
• ½ teaspoon salt & ¼ teaspoon pepper – Essential for seasoning. Adjust to taste.
• 1 ½ cups ham, diced – A great way to use leftover ham. Cooked bacon or ground turkey can be used instead.
• 1 cup Swiss cheese, grated – Add a nutty flavor to the quiche. Gruyère is another fantastic option.
• 1 cup mild cheddar cheese, grated – Adds a creamy, sharp bite. Monterey Jack or Colby can step in here.
• 1 frozen deep-dish pie crust – This is the shortcut that makes this quiche so easy. You can also use a homemade crust.
• Chives or green onions, chopped (optional) – Adds a pop of freshness and color.

Sauté  – Melt the butter over medium heat in a small pan or saucepan. Add the onions and cook until tender (about 2-3 minutes). Stir in the garlic and cook for 30-60 seconds until fragrant. Let cool slightly.

Make the custard – In a large bowl, whisk the eggs until lightly beaten. Add the half-and-half, thyme, salt, and pepper, whisking until thoroughly combined.

Assemble the filling – Stir in the cooked onion mixture, diced ham, and both cheeses.

Fill – Place the pie crust on a baking sheet. Pour the mixture into the frozen pie crust, spreading everything evenly.

Bake – Bake for 40-45 minutes in a 375°F (190°C) preheated oven, or until the center is set and a knife inserted comes out clean.

Serve and enjoy – Let the quiche cool for 10 minutes before slicing. Serve warm, at room temperature, or even chilled. Garnish with chives or green onions if desired.
