Whole milk is a simple substitute for heavy cream in quiche: use 1½ cups (360 ml) milk with 4 large eggs for a tender, sliceable filling. This spinach-and-cheese quiche keeps the familiar savory custard texture, though it will be a little less rich than one made with cream.
Ingredients
- 1 refrigerated 9-inch pie crust (about 230 g), ready to bake
- 1 tablespoon (15 ml) olive oil
- ½ cup (75 g) finely chopped yellow onion
- 3 cups (90 g) fresh baby spinach, roughly chopped
- 4 large eggs (about 200 g without shells)
- 1½ cups (360 ml) whole milk
- 1 cup (100 g) shredded Gruyère or Swiss cheese
- ½ teaspoon (3 g) fine salt
- ¼ teaspoon (0.5 g) freshly ground black pepper
- ⅛ teaspoon (0.25 g) ground nutmeg, optional
Instructions
- Heat the oven and prepare the crust. Set a rack in the middle of the oven and heat it to 375°F (190°C). Fit the refrigerated crust into a 9-inch pie plate, following the package directions if they differ. Line the crust with parchment and fill it with pie weights or dry beans. Bake for 10 minutes, then carefully lift out the parchment and weights and bake for 5 minutes more. The bottom should look dry but not deeply browned. Set the crust aside while you prepare the filling.
- Cook the vegetables. Warm the olive oil in a skillet over medium heat. Add the onion and cook for about 4 minutes, stirring, until softened. Add the spinach and cook for 2 to 3 minutes, turning it as it wilts. Transfer the vegetables to a plate and let excess moisture evaporate for a minute or two. If the spinach looks wet, gently press it with the back of a spoon; too much liquid can make the custard watery.
- Mix the milk-and-egg custard. In a medium bowl, whisk the eggs just until the yolks and whites are blended. Whisk in the whole milk, salt, pepper, and nutmeg, if using. Avoid whipping in lots of air, which can create a puffy surface that falls as the quiche cools. Stir in the shredded cheese, or scatter it over the crust for a more distinct cheese layer.
- Fill the crust. Spread the spinach and onion evenly over the par-baked crust. Pour the egg-and-milk mixture over the vegetables. If the pie plate is very full, place it on a rimmed baking sheet before moving it to the oven; this makes spills easier to catch.
- Bake until just set. Bake at 375°F (190°C) for about 35 to 40 minutes. The edges should be set, while the center may still have a slight, gentle wobble. Check the center with a food thermometer: egg dishes should reach the USDA FSIS safe minimum internal temperature of 160°F (71°C). If the crust browns too quickly, loosely cover its edge with foil for the last part of baking.
- Rest before slicing. Set the quiche on a cooling rack for 15 minutes. This resting time helps the custard finish setting, so slices hold together instead of running onto the plate. Serve warm or at room temperature.
Tips
- Choose whole milk for the closest everyday swap. It gives the eggs enough liquid to form a tender custard, with less richness than heavy cream. If you have half-and-half, use the same 1½-cup (360 ml) amount for a closer, creamier result. Two-percent milk also works, though the filling will be lighter and can seem less silky.
- Keep the filling relatively dry. Spinach, mushrooms, zucchini, and other vegetables release water as they cook. Sauté watery vegetables first and let steam escape before adding them. For frozen spinach, thaw it completely and squeeze out as much liquid as possible before measuring or adding it.
- Do not overbake the custard. A firm, browned center usually means the eggs have cooked too long and may turn rubbery. Look for set edges and a slight wobble in the middle, then confirm the center reaches 160°F (71°C) with a thermometer. The short rest firms the slices further.
- Blind-bake the crust and protect its rim. Par-baking helps keep the bottom from becoming soggy under a milk-based custard. If you use a frozen crust, follow its package directions for thawing and baking; crust thickness and recommended times vary.
Serving Suggestions
Serve a warm slice for brunch or a simple lunch alongside a crisp green salad dressed with vinaigrette. Fruit, roasted tomatoes, or lightly dressed sliced cucumbers also balance the savory cheese and custard without making the plate feel heavy. For a more substantial meal, add roasted potatoes or a bowl of vegetable soup.
Quiche is also good at room temperature, which makes it useful for a buffet or a make-ahead meal. Let it rest for the full 15 minutes before cutting, and use a sharp knife to make clean wedges. If you are serving it alongside other dishes, cut smaller slices; the filling is rich enough to work as one part of a larger spread.
Variations
Use half-and-half: Replace the whole milk with 1½ cups (360 ml) half-and-half. The custard will be richer and closer to a traditional heavy-cream version, without changing the egg quantity or method.
Make it with evaporated milk: Use 1½ cups (360 ml) unsweetened evaporated milk in place of the whole milk. It creates a fuller-tasting custard than ordinary milk. Do not use sweetened condensed milk, which is sugary and not a suitable savory substitute.
Try a dairy-free filling: Use 1½ cups (360 ml) plain, unsweetened, unflavored soy milk or oat milk. Choose an unsweetened product, since vanilla or sweetened varieties can give the quiche an unwanted flavor. The filling may be less rich and its set can vary by brand, so check the center temperature and allow the full resting time. Use dairy-free cheese or omit the cheese if needed.
Change the vegetables and cheese: Replace the spinach with 1 cup (about 100 g) cooked mushrooms, broccoli, or chopped roasted peppers. Keep cooked vegetables to a similar volume and drain them well. Cheddar, feta, or a mild goat cheese can replace Gruyère; salty cheeses such as feta may call for a little less salt in the custard.
Storage and Reheating
Refrigerate leftover quiche within 2 hours of baking. Cover the pie plate or transfer slices to an airtight container; refrigerate for 3 to 4 days. The crust softens somewhat as it sits, but the filling keeps well and remains easy to portion when cold.
To reheat a slice, place it on a baking sheet and warm it in a 325°F (165°C) oven for about 15 to 20 minutes, depending on its size and starting temperature. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. A microwave works for a quick portion, but it can soften the crust and heat unevenly; use short intervals and check that the center is hot. For longer storage, wrap cooled slices tightly and freeze for up to 2 months for best quality. Thaw in the refrigerator before reheating.
Frequently Asked Questions
Can I use milk instead of heavy cream in quiche?
Yes. Whole milk works well in this recipe and produces a tender, sliceable custard that is less rich than one made with heavy cream. Use 1½ cups (360 ml) milk with 4 large eggs for a 9-inch quiche. Low-fat milk can also work, but the finished texture may be less creamy.
What is the best substitute for heavy cream in quiche?
For a readily available option, use whole milk. Half-and-half is the closest simple substitute if you want a richer filling. Plain, unsweetened soy or oat milk can work for a dairy-free version, although the taste and texture can vary by product.
Can I use milk and butter as a heavy cream substitute?
It is usually easier to use whole milk or half-and-half directly. Butter stirred into milk does not behave exactly like cream in a custard and may separate or leave a greasy texture. Since eggs provide the structure in quiche, you do not need to add butter to make this milk-based filling set.
Why did my quiche turn watery?
Excess moisture from vegetables is a common reason. Cook vegetables such as spinach and mushrooms before adding them, and drain or squeeze out liquid from thawed frozen vegetables. A quiche can also seem watery if it is cut before resting or if it is underbaked; check that the center reaches 160°F (71°C) and let it stand for 15 minutes.
Can I make this quiche ahead of time?
Yes. Bake it, cool it, and refrigerate it within 2 hours. It keeps for 3 to 4 days in the refrigerator. Reheat portions in the oven until they reach 165°F (74°C), or serve the quiche cold or at room temperature if it has been kept safely chilled.
