English Breakfast Quiche with Sausage and Mushrooms

English breakfast quiche brings the familiar cooked-breakfast combination of sausage, bacon, mushrooms, tomatoes and eggs together in a crisp pastry crust. This version is baked as a savory custard pie, making it easy to slice for brunch or prepare ahead; fillings vary, so you can adjust them to suit your table.

Ingredients

1 unbaked 9-inch (23-cm) pie crust, homemade or store-bought (about 9 oz/255 g)
2 pork breakfast sausages, casings removed, about 4 oz (115 g)
3 slices bacon, about 3 oz (85 g), cut into small pieces
1 cup (75 g) sliced button or cremini mushrooms
½ cup (75 g) cherry tomatoes, halved, or 1 small tomato (about 100 g), seeded and diced
¼ cup (25 g) thinly sliced green onions
4 large eggs (about 200 g without shells)
¾ cup (180 ml) whole milk
½ cup (120 ml) heavy cream
1 cup (100 g) grated mature cheddar cheese
¼ teaspoon (1.5 g) fine salt, plus more to taste
¼ teaspoon (0.5 g) freshly ground black pepper
⅛ teaspoon (0.3 g) ground nutmeg, optional
1 teaspoon (5 ml) neutral oil, only if the pan is dry

Instructions

Heat the oven and prepare the crust. Set a rack in the lower-middle position and heat the oven to 375°F (190°C). Fit the crust into a 9-inch (23-cm) pie plate, crimp the edge, and prick the base several times with a fork. Line it with parchment and fill with pie weights or dried beans. Bake for 15 minutes, then carefully remove the weights and parchment and bake for another 5 minutes. Set aside. Keep the oven on.
Cook the meat. While the crust bakes, place a skillet over medium heat. Add the bacon and cook for about 5 minutes, stirring occasionally, until browned and crisp. Transfer it to a paper-towel-lined plate, leaving about 1 tablespoon of rendered fat in the pan. Add the sausage and cook for 6–8 minutes, breaking it into small pieces, until no pink remains and a food thermometer reads 160°F (71°C); this is the USDA FSIS safe minimum temperature for ground meat. Transfer the sausage to the plate.
Soften the vegetables. Add the mushrooms to the skillet and cook for 4–5 minutes, stirring, until browned and their released liquid has evaporated. Add a teaspoon of oil if the pan looks dry. Stir in the tomatoes and cook for 1 minute, just to remove some surface moisture. Take the pan off the heat.
Mix the custard. Whisk the eggs, milk, cream, salt, pepper and nutmeg in a bowl until evenly combined. Avoid beating in lots of air, which can make the baked filling puff and then sink. Stir in the cheddar, green onions, cooked sausage, bacon and vegetables.
Fill and bake. Pour the mixture into the warm crust and set the pie plate on a baking sheet to catch any drips. Bake at 375°F (190°C) for 35–40 minutes, until the edges are set and the center has only a slight wobble. Check the center with a food thermometer; egg dishes need to 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.
Rest before slicing. Set the quiche on a rack for 10 minutes so the custard can finish setting. Cut into six wedges and serve warm, or let it cool further before refrigerating.

Tips

Prevent a soggy base: Blind-baking the crust and cooking the mushrooms until their liquid evaporates are both worthwhile. Seed a juicy tomato before chopping it, and avoid adding wet vegetables straight from the pan.
Keep the filling balanced: The sausage and bacon are already salty, so taste the cooked filling before adding extra salt. If using a salty cheese or cured meat, reduce the measured salt slightly.
Crust options: A frozen 9-inch crust can be used; follow its package directions for partial baking, and check whether it needs thawing. For a crustless quiche, grease a 9-inch pie plate well and bake the filling directly in it; it may set a little sooner.
Plan the timing: The meat and vegetables can be cooked a day ahead and refrigerated. Cool them promptly, keep them covered, and mix with the egg custard just before baking.

Serving Suggestions

Serve a warm wedge with toast, buttered English muffins or roasted breakfast potatoes for a substantial brunch. A simple green salad, dressed lightly with lemon or vinegar, balances the richness; fruit or grilled tomatoes also make an easy side. For a buffet, cut the quiche into smaller slices and serve it warm or at room temperature, but do not leave it out for more than 2 hours.

Variations

For a meat-free version, omit the sausage and bacon and use about 1½ cups (225 g) of vegetables, such as mushrooms, spinach and sautéed onions. Cook vegetables that release water before adding them so the custard stays firm. You can replace cheddar with an equal amount of grated Lancashire, mature Gouda or another firm cheese; each changes the flavor and saltiness slightly.

To bring in baked beans, spoon ⅓ cup (about 85 g) of thick, drained beans over the cooked filling before adding the custard. Use only a modest amount because their sauce can make the quiche wet and sweet. For a lighter filling, replace the cream with more whole milk, though the texture will be less rich and slightly softer. A pinch of dried thyme or mustard powder is another easy way to vary the seasoning.

Storage and Reheating

Refrigerate leftover quiche within 2 hours of baking, in a covered container or wrapped pie plate. It keeps for 3–4 days in the refrigerator. For longer storage, wrap individual cooled slices airtight and freeze for up to 2 months; thaw overnight in the refrigerator for more even reheating.

Reheat slices in a 325°F (165°C) oven for about 15–20 minutes, loosely covered with foil if needed to prevent over-browning. Check that leftovers reach 165°F (74°C) throughout, the recommended reheating temperature. A microwave works for a single slice—heat in short intervals and check the center, though the crust will be softer. Discard quiche left at room temperature for more than 2 hours, or more than 1 hour when the surrounding temperature is above 90°F (32°C).

Frequently Asked Questions

Can I make English breakfast quiche the day before?
Yes. Bake it fully, cool it, and refrigerate it covered within 2 hours. Reheat slices in the oven until they reach 165°F (74°C), or serve it cold if you prefer; avoid holding it at room temperature for an extended period.

How can I tell when the quiche is done?
The outer portion should look set, and the center should have only a small wobble rather than a liquid ripple. For food safety, confirm with a thermometer inserted into the center: the egg filling must reach 160°F (71°C). It will firm further as it rests.

Can I use a different kind of sausage?
Yes. Pork breakfast sausage is typical for this version, but you can use another breakfast-style sausage. If it is raw ground meat, cook it completely to 160°F (71°C) before adding it. Pre-cooked sausage should be heated through in the skillet and cut into small pieces.

Why is my quiche watery?
Common causes are mushrooms or tomatoes added while still wet, excess liquid from vegetables, or an underbaked center. Cook vegetables until their moisture has mostly evaporated, drain any excess grease, and bake until the center reaches 160°F (71°C).

Can I bake it without pastry?
Yes. Grease the pie plate thoroughly, add the filling directly, and begin checking for doneness earlier than the crusted version. The exact time depends on the dish and the filling depth, so use the 160°F (71°C) center temperature rather than appearance alone.

Can I freeze a whole quiche?
Yes. Cool it completely, wrap it tightly, and freeze for up to 2 months for best quality. Thaw it in the refrigerator overnight, then reheat until the center reaches 165°F (74°C). Freezing can soften the crust slightly, but the quiche remains convenient to portion and serve.
