Roast Beef Quiche: Ingredients & Equipment
For this Roast Beef Quiche recipe, you’ll need …
Ingredients
- pastry pie crust – you’ll want a 9-inch one. You can make your own or get it premade, whichever is easiest for you!
- large eggs – hard to make a quiche without them!
- cooked roast beef and green onions – your first delicious quiche fillings.
- green pepper, milk, cheddar cheese, flour, and steak sauce – more flavors and additions for the quiche.
- dill weed, dried basil, dried oregano – your quiche herbs and seasonings.
- salt and pepper – to taste.
Equipment
- aluminum foil – this is for baking your crust!
- bowl – for making your quiche mixture, of course.

How to make Roast Beef Quiche
First, prep your crust. Preheat your oven to 400° F. Prick the crust several times. Loosely ball up a piece of aluminum foil (about 12×18-inch) and place it in the center of the crust. Bake the crust for 5 minutes. Carefully remove the foil ball, and bake the crust for 5 minutes longer.
Second, make your filling. Reduce the oven heat to 375° F. Sprinkle beef and green onions into the crust. In a bowl, beat flour, eggs, milk, steak sauce, dill weed, basil, oregano, and salt. and pepper. Add green peppers and cheese and mix it well. Pour the filling into the crust.
Finally, bake the quiche and enjoy! Bake your quiche for 25-30 minutes or until the center is set. Allow it to stand for 10 minutes before cutting, then chow down!

This Roast Beef Quiche can be reheated in the oven at 350°F for 10-15 minutes, in the microwave for 1-2 minutes, or until heated through.
I recommend …
– mozzarella cheese (it becomes so gooey!), pepper jack, blue cheese, or gruyere
– mushrooms

– bacon or ham (especially if the bacon is thick)
– chopped, roasted, fried, or boiled potato cubes
– carrots
– sweet potatoes

I have never seen quiche with roast beef. I'll have to try it. I’m so glad you linked this up at One Creative Weekend!
I love being creative with leftovers but I always have the hardest time finding roast beef recipes using leftovers that seem appealing to me. This looks delicious and I can't wait to try it 🙂
Found you from Blessed with Grace's link up. This looks delicious and sounds like a perfect way to use leftover roast beef. Pinning it now! 🙂
What a great quiche! I love that you've re-purposed your leftovers to make a new meal. Our leftovers are usually put into individual servings and packed with lunch.

Wow, I never thought of putting roast beef into a quiche. Great way to use up leftovers!
Hello.
My first time here. Visiting from Kathe's blog hop.
My wife doesn't like to throw away food and always surprises me with leftovers that to me always taste like something new (smile). I love quiche, but I've never had it with roast beef before. This looks delicious. Can you see me doing some virtual tasting? (LOL)
Thanks for sharing.

I love quiche but hadn't thought about using up leftovers in one. Thanks so much for sharing on Tout It Tuesday. Hope to see you tomorrow.
Sounds delightful!! Thanks for linking up to Tasty Thursdays at The Mandatory Mooch. Hope you will link up again this week. The party will be live tonight. http://www.mandatorymooch.blogspot.com
Thanks, Nichi
Made this tonight and it was quite tasty- the A1 sauce really gives it a great flavor. I was wondering though when you put the cheese in. You didn't mention that and I added it on top of the beef but had trouble getting the egg mixture to set then. Do you usually put it on top?
I fixed that on the blog and printable 🙂 Thank you for letting me know! Depending on your oven, you may need to cook it a little longer. The center should be set before it comes out of the oven – and it needs to rest before cutting. Hope this helps!
Trying this tonight with canned venison instead of roast beef. No steak sauce, so substituting 1/2 and 1/2 ketchup and Worcestershire. 🙂 Thanks for the inspiration.
Awesome! I would love to hear how it is with those changes! 🙂
