35 Minute Vegetable Pie Recipe

Don't be fooled by the name of this recipe. Instead of being impossible, recipe developer and registered dietician Kristen Carli tells Mashed, "Traditionally, an impossible vegetable pie uses Bisquick, and this ingredient makes a crust on the pie while it bakes. It's impossibly easy!" Indeed, you would have a hard time messing up this egg-based dish, which also incorporates colorful vegetables and savory cheese. 

Beyond just the simplicity of impossible vegetable pie, we love its versatility, with Carli noting about the dish, "The texture is a mix between a quiche and frittata." Therefore, this meal is brilliant at breakfast, the bomb at brunch, lovely at lunchtime, and divine for dinner. 

It's also a win how you may not even have to shop for ingredients if you want to whip up impossible veggie pie today. All that you need are a few kitchen staples and some fresh vegetables as well as about half an hour of your time.

Shop for your ingredients

To fix an impossibly easy meal, all you need is a bunch of asparagus, which you will trim the ends off of — they're rough and not easy to chew — and chop. Gather from the kitchen or quickly pick up at the store the following as well: a red onion, a red pepper, shredded three cheddar cheese, whole milk, three eggs, Bisquick — you only need three-quarters of a cup, so a partially used box you already have in the pantry ought to do — salt, and pepper. Want to kick up the heat on this recipe? Try adding some red pepper flakes!

We asked Carli about her choice of cheese, and as she explained, a great complement to the eggs and veggies is three cheddar cheese. "This is a mix of mild cheddar, sharp cheddar, and white cheddar," she said. 

Okay, now you are ready to assemble your impossible pie.

Chop your veggies

Step one: Preheat your oven to 400 degrees Fahrenheit. Now, spray a nine-inch cake pan with nonstick cooking spray. And get a load of this: You will build your pie in this dish, with only one other bowl required to make your pie. Yup, when it comes to clean-up, that is easy, er, impossible, too. 

Next, chop a quarter of your red onion, a whole red pepper, and that asparagus. Mix the veggies right in the cake pan. Optional: Take a moment to admire the colorful array of vegetables you are about to enjoy. As for why she selected these specific veggies, Carli noted, "I chose asparagus because to me it is the ideal veggie to pair with eggs, especially in spring." She added, "Red onion provides flavor, while bell pepper provides crunch."

Now, it's time to mix up the rest of your ingredients. In a medium-sized bowl, add your shredded cheese, the milk, eggs, Bisquick, salt, and pepper. Carli recommends using a fork or whisk to combine everything together.

Combine your ingredients

Finally, you will pour the egg and Bisquick mixture over the top of those colorful, crunchy, flavorful veggies in the cake pan. Season with salt and pepper, and bake the pie for 30 minutes, with Carli noting this dish is virtually impossible to get wrong. "It really is that easy!" she said. 

Once the pie is baked, pair it with some roasted potatoes, a side salad, or enjoy the dish alone. Might we suggest you keep a bottle of your favorite hot sauce on hand while serving?

And P.S.: There's no need to tell your family or friends how easy this meal was to make. Your secret is safe with us!
