Italian vegetable quiche is a tasty combination of spinach, mushrooms, sweet bell peppers, and zucchini baked in a pie plate with no crust. It gets spiced up with lots of dill weed and the result is delicious.
“
Years ago, when Mary Jo said that she was making Italian vegetable quiche, I quickly turned up my nose and said I’m not eating that! How could anything called Vegetable Quiche be any good for someone who wants meat and potatoes all the time?
Well, that was a long time ago, and when the aromas of the quiche filled our kitchen, I was really surprised. Still leery of the name, the first bite was a revelation.
Although we call it Italian Vegetable Quiche, we always have ham in it, (or you could keep it vegetarian without the meat and add imitation bacon to kick up the flavor). And it is Crustless Vegetable Quiche, so it is simple to make.
Vegetable Quiche with Spinach, Mushrooms and Zucchini
If you’ve been looking at recipes and wondered how things would taste and never tried the recipes, try this one because it is killer, and you won’t be disappointed. One recipe will serve four people, each having a little for seconds, (because you’ll want seconds). Serve with a fruit salad, some good bread and white wine.
Ingredients For The Quiche
- ยฝ lb fresh sliced mushrooms
- 1 medium green, red, or yellow bell pepper, diced
- 1 small to medium zucchini, thinly sliced
- 2 tbsp olive oil
- 1 cup cooked ham, diced
- 1 lb. ricotta cheese
- 1 cup mozzarella cheese, shredded
- 3 eggs, slightly beaten
- 1 14-16 oz can spinach, drained and pressed dry as possible
- 1 1/2 tbsp dill weed
- 1 tsp kosher salt
- 1 tsp black pepper
Make Your Own Ricotta Cheese
I told MaryJo that I was going to make this, and she got excited. I hadn’t made it in a while. So, MaryJo bought a gallon of whole milk and set out to make ricotta cheese. I became an interested on-looker.
She put 1/2 gallon of whole milk and 1/4 cup of heavy cream into a small stock pot and put it on the stove and brought it up to a boil and removed it from the burner. Then 1 1/2 teaspoons of citric acid gets dissolved in 1/4 cup of water, (vinegar or lemon juice is also used in some recipes). The acid is stirred into the milk and magically, the milk starts to separate into curds, (the ricotta), and whey.
The curds get strained with cheesecloth and the whey, in our case, gets saved for making bread. It’s a win, win recipe.
Bon Appetit magazine has an easy recipe for making Ricotta Cheese.
Preparing the Quiche
Start with a good-sized skillet and add 2 tablespoons of olive oil. I like to add the mushrooms first and let them cook until they release their moisture, which takes 5 or 6 minutes. Then add the peppers and zucchini. Cook them to soften slightly, another 5 or 6 minutes. The zucchini especially does not have to be too soft because it gets baked and finished in the pie plate.
Add the ham and put this mixture in a large bowl and let cool. Once cooled, add all the other ingredients and fold together. Pour into an oiled 9 ยฝ inch quiche pan or pie plate.
Bake 45 to 55 minutes at 350 degrees, until it starts browning on the edges. Let it rest for 15 to 20 minutes, then slice and serve. (You may have too much for the pan, just take another small oven safe container and bake the rest).
If you have any leftovers, they can be frozen or reheated in the oven or microwave.
Try this and I think that you will agree that it is delicious.

- Once cooled, add the remaining ingredients and fold together. Be sure to drain the spinach well and squeeze as much moisture out as you can. I use paper towels for this.

- Let cool 15 to 20 minutes before serving.

- Leftovers are delicious and can be reheated in the microwave or frozen in an air-tight container for up to 3 months.
- Omit the ham for a vegetarian version.

You may be surprised at canned spinach in this recipe, but years ago when we first got this recipe, the only way you could have fresh spinach is if you grew it yourself and I don’t ever remember seeing frozen spinach with the other frozen vegetables, so canned was the only option avaiilable to us.
And these days, with all the recalls of fresh greens due to ecoli contamination, canned and frozen spinach are equally good options, but cook frozen spinach first, then continue with the recipe.

When I first got the recipe from Andy, I was really skeptical about the dill weed, but that’s what really makes this dish. It’s soooo good!
