Why Make Vegetable Quiche with Spinach, Mushrooms
This quiche gives you a lot of value from simple, everyday ingredients. Eggs and cheese add protein and richness. Spinach and mushrooms bring earthy flavor, while cherry tomatoes add a sweet pop. The mix feels cozy and balanced, not heavy. You can make it with a store‑bought crust to save time or a homemade crust if you want to go all in.
It’s a great year‑round recipe. In spring and summer, cherry tomatoes and tender spinach are at their best. In fall and winter, mushrooms add deep, savory notes. The quiche is also flexible. Swap the cheese, change the herbs, or go crustless if you like. It reheats well and holds up in the fridge, so it’s perfect for meal prep. Make it for a weekend brunch or bake it on Sunday and enjoy easy slices throughout the week.

How to Make Vegetable Quiche with Spinach
Step-by-Step Cooking Instructions
- Heat the oven to 375°F (190°C). Place a rack in the center.
- Blind‑bake the crust: Prick the bottom with a fork. Line with parchment and fill with pie weights. Bake 12–15 minutes. Remove weights and parchment; bake 5 more minutes until lightly golden. Cool slightly.
- Cook the vegetables: Heat oil in a large skillet over medium. Sauté onion 2 minutes. Add mushrooms; cook until browned and their liquid evaporates, 5–7 minutes. Stir in garlic 30 seconds. Add spinach and cook until wilted, 1–2 minutes. Season with a pinch of salt and pepper. Transfer to a plate to cool. Pat tomatoes dry.
- Make the custard: In a bowl, whisk eggs, half‑and‑half, salt, pepper, thyme, and nutmeg until smooth.
- Assemble: Sprinkle half the cheese over the crust. Add the mushroom‑spinach mix, then scatter tomatoes. Top with remaining cheese. Pour in the custard (do not overfill).
- Bake 30–35 minutes, until the edges are set and the center has a slight jiggle. If the crust browns too fast, shield with foil.
- Rest 10–15 minutes before slicing. Serve warm or at room temperature.
Tips for Texture, Timing & Tools
- Keep it crisp: Blind‑bake the crust and pre‑cook veggies to drive off moisture.
- Dry tomatoes: Seed and pat them dry to avoid a watery quiche.
- Doneness check: The center should jiggle slightly; internal temp about 165°F (74°C).
- Pan choice: Glass makes it easy to see browning; metal bakes a bit faster. A preheated baking sheet under the pie plate helps crisp the bottom.
- Rest time: Let it stand before slicing so it sets cleanly.
Storage & Reheating
How to Store It Right
- Refrigerate: Cool fully. Cover tightly or store slices in airtight containers for 3–4 days.
- Freeze: Wrap slices in plastic, then foil, or use freezer bags. Freeze up to 2 months. Label and date.
Reheating Without Losing Flavor
- Oven/toaster oven: 325°F (165°C). Slices 10–15 minutes; whole quiche 20–25 minutes. Cover loosely with foil.
- Air fryer: 320°F (160°C) for 6–8 minutes for a slice.
- Microwave: 50% power, 60–90 seconds per slice to avoid rubbery eggs.
A Dish Worth Making Again and Again
This quiche keeps its flavor and texture after chilling and reheating. It’s a reliable, make‑ahead option for busy weeks and an easy win for brunch with friends.
FAQs
Can I make this quiche ahead of time?
Yes. Bake it, cool it, and refrigerate up to 2 days. Reheat at 325°F (165°C) until warmed through. Or prep components ahead: blind‑bake the crust and cook the veggies, then assemble and bake the day you serve.
Can I use frozen spinach?
Yes. Thaw it, squeeze out as much liquid as possible, and measure about 3/4 to 1 cup packed. Add it to the skillet just to warm through before assembling.
How do I prevent a soggy bottom?
Blind‑bake the crust, pre‑cook and cool the veggies, pat tomatoes dry, and don’t overfill with custard. A preheated baking sheet under the pie plate also helps crisp the base.
What cheeses work best in this quiche?
Gruyère or Swiss for classic quiche flavor, sharp cheddar for bolder taste, or a mix. Parmesan adds a savory boost. Feta or goat cheese give tang but use a lighter hand so the custard still sets well.
