Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9-inch tart pan or pie dish.
Place the pie crust into the pan and gently press it against the bottom and sides.
Prick the bottom several times with a fork.
2. Blind-Bake the Crust
For a crispier crust, cover the pastry with parchment paper and add pie weights or dried beans.
Bake for 10–12 minutes.
Remove the parchment and weights, then return the crust to the oven for another 3–5 minutes, until lightly golden.
Remove from the oven and set aside.
3. Brown the Ground Beef
Heat the olive oil in a large skillet over medium-high heat.
Add the diced onion and cook for 2–3 minutes, until softened.
Add the ground beef.
Cook for 6–8 minutes, breaking the meat apart with a wooden spoon, until browned and fully cooked.
Add the minced garlic, thyme, paprika, salt, and black pepper.
Cook for another 1–2 minutes.
Drain any excess grease from the skillet.
Set the beef mixture aside to cool slightly.
4. Cook the Zucchini
Using the same skillet, add the thinly sliced zucchini.
Cook over medium heat for approximately 4–5 minutes, stirring occasionally.
The zucchini should become slightly tender but should not be mushy.
Transfer the zucchini to a plate lined with paper towels.
Gently pat away excess moisture.
5. Prepare the Egg Custard
In a large mixing bowl, whisk together:
- 4 eggs
- 1 cup heavy cream
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- A pinch of nutmeg
Whisk until smooth and well combined.
Do not over-whisk, as you do not need to incorporate a lot of air.
6. Assemble the Quiche
Sprinkle about 1/2 cup of shredded Gruyère over the bottom of the partially baked crust.
Add the seasoned ground beef and spread it evenly.
Arrange the zucchini slices over the beef.
Slowly pour the egg custard over the filling.
Sprinkle the remaining 1/2 cup Gruyère evenly over the top.
7. Bake the Quiche
Carefully place the quiche in the preheated oven.
Bake for approximately 30–35 minutes.
The edges should be set, the cheese should be golden, and the center should have only a very slight jiggle.
If the crust becomes too brown before the filling is finished, loosely cover the edges with aluminum foil.
8. Rest Before Serving
Remove the quiche from the oven.
Allow it to rest for 10–15 minutes before slicing.
This gives the custard time to finish setting and makes the quiche easier to cut.
Slice into wedges and serve warm or at room temperature.
Best Tips for Perfect Beef Quiche
Drain the Beef Well
Ground beef can release quite a bit of fat during cooking. Drain excess grease before adding it to the crust so the quiche does not become greasy.
Remove Moisture From the Zucchini
Zucchini contains a lot of water. Cooking it first and patting it dry helps prevent a watery quiche.
Don’t Skip the Pre-Bake
Blind-baking the crust helps create a crisp, golden base instead of a soggy pastry.
Don’t Overcook the Eggs
Remove the quiche when the center is just set. Overbaking can make the custard rubbery.
Let It Rest
A short resting period allows the filling to firm up and makes cleaner slices.
Best Ingredient Options
Ground beef: An 80/20 blend provides excellent flavor and moisture. Leaner beef can also be used.
Cheese: Gruyère is ideal, but Swiss, cheddar, mozzarella, provolone, or Monterey Jack can work.
Cream: Heavy cream creates the richest custard. Half-and-half makes a slightly lighter version.
Vegetables: You can add mushrooms, spinach, bell peppers, or extra zucchini.
Recipe Variations
Beef, Zucchini and Mushroom Quiche
Sauté 1 cup sliced mushrooms with the beef and onions for a richer, more savory filling.
Cheesy Beef and Zucchini Quiche
Add 1/2 cup shredded mozzarella along with the Gruyère for an extra-gooey cheese filling.
Spicy Beef Quiche
Add 1/4 teaspoon red pepper flakes or a small amount of finely diced jalapeño to the beef mixture.
Mediterranean Beef Quiche
Add dried oregano, chopped parsley, and a few tablespoons of crumbled feta cheese.
Crustless Beef and Zucchini Quiche
Skip the pastry crust and pour the prepared filling into a well-greased 9-inch pie dish.
Bake until the center is fully set.
What to Serve With Beef and Zucchini Quiche

Make-Ahead Instructions
You can prepare the beef and zucchini filling up to 1 day in advance.
Cook the beef and zucchini, allow them to cool completely, and store them separately in the refrigerator.
When ready to bake, prepare the custard, assemble the quiche, and bake as directed.
You can also bake the entire quiche one day ahead and reheat it before serving.
Storage
Allow leftover quiche to cool before storing.
Place it in an airtight container or cover the pie dish tightly.
Refrigerate for 3–4 days.
Do not leave egg- and dairy-based quiche at room temperature for extended periods.
Reheating
For the best texture, place individual slices in a 325°F (165°C) oven.
Heat for approximately 10–15 minutes, or until warmed through.
You can also microwave individual slices, but use short intervals to avoid overcooking the custard.
Freezing
The baked quiche can be frozen for up to 2 months for the best quality.
Allow it to cool completely.
Wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag or container.
Thaw overnight in the refrigerator.
Reheat in a 325°F (165°C) oven until hot.
Common Mistakes to Avoid
Adding Wet Zucchini
Excess zucchini moisture can make the quiche watery.
Always sauté and drain the zucchini first.
Not Draining the Beef
Too much beef fat can make the crust greasy.
Drain the cooked ground beef before assembling the quiche.
Overfilling the Crust
Do not fill the pastry all the way to the rim. Leave a little space for the custard to expand during baking.
Overbaking
A perfectly cooked quiche should have a tender, creamy center.
Remove it from the oven once the center is just set.
Cutting Too Soon
Rest the quiche for at least 10 minutes before slicing.

Frequently Asked Questions
