Caramelized Onion, Zucchini, Tomato and Mushroom Tart

September 30, 2013Teresa

Caramelized Onion, Zucchini, Tomato and Mushroom Tart is awesome! This is another of those “to-die-for” tarts I made a couple of weeks ago. Caramelized Onions, slices of zucchini, tomatoes and mushrooms filled my Homemade Pie Crust-lined tart pan. The veggies were seasoned with lots of delicious Italian seasonings, and smothered in four different hard cheeses: Asiago, Parmesan, Fontina, and Pecorino Romano.

Yum, yum, good was the reaction from our guests when I served this wonderful tart. This scrumptious tart cannot be classified with a “quick and easy ” description since it is a lot more involved and time-consuming. But it can certainly be classified as one of the BEST veggie tarts you’ll ever eat! Those of you still reaping veggies like tomatoes, onions, or zucchini from your garden will love being able to use them in this tasty recipe.

This lovely tart can be made as a side dish or as a main dish–particularly on Meatless Mondays. It’s very hearty, filling and satisfying, plus it just pops with flavor on those taste buds. It’s also a great breakfast entree.

It’s not excessively high in calories and is certainly a lot healthier than tarts or pies made with canned soups, gravy mix, ranch dressing mix and other ingredients with a lot of MSG, preservatives, and fillers. I know those foods have their place in cooking but I try to limit my use of them as much as possible. When I do, I find I don’t crave food all the time or have such an enormous appetite as when I eat something with MSG, sugar, or high fructose corn syrup.

Making up a Caramelized Onion, Zucchini, Tomato and Mushroom Tart is a great way to use up garden produce. If you don’t have time to make your own Homemade Pie Crust, than simply use a store bought crust.

Here are a few recommendations when making this tart: First, plan plenty of time because it will take about an hour to caramelize the onions fully and you need to lay the tomatoes and zucchini out on the counter to drain for at least an hour as well. This will help prevent too much liquid in the pie which causes a soggy crust.

Second, don’t place any of the filling in the pie crust until it is all ready to go (including having the oven at the preheated temperature). Leaving any kind of filling ingredients in a tart or pie shell and not baking immediately will cause a soggy crust.

Third, while I provide some detail for caramelizing the onions, if you need more explicit directions on how to do this than check out this post. Fourth, don’t make the pie crust for the tart until after the onions are caramelized and the tomatoes and zucchini have drained. Otherwise, the pie crust will dry out and get brittle.

If you’re looking for a marvelous tart recipe with radically amazing taste than please consider making up a Caramelized Onion, Zucchini, Tomato and Mushroom Tart sometime soon. Neither you, nor your family (or guests) will be disappointed with this sensational tart. The flavors are delectable and you will berate yourself for making ONLY one! 🙂

Usually I send a lot of leftovers home with our guests, but I was rather selfish with this tart and kept all the leftovers for my lunch the next day! This tasty tart even reheats well. You can also freeze the tart before or after baking and bake again (which is what I did for the third kind of tarts I made–which will be posted at a later time)!

Here’s what I did.

Fit Homemade Pie Crust or store bought pie crust in tart dish. Trim off edges. I highly recommend you don’t make the crust until the onions are caramelized and the tomatoes and zucchini have drained so the crust doesn’t dry out.

Slice tomatoes and set out on paper towels to drain. Sprinkle very generously with salt. The tomatoes need to drain at least an hour. Mine were actually on the counter about three hours before I used them.

Add a little olive oil to a large skillet and begin sauteing the onions over a medium heat.

Continue cooking and turning occasionally for about a half hour. Be careful that the heat is not so hot that the onions scorch, or that you turn the onions so frequently that they don’t brown and caramelize.

You may have to add a little water to keep them from sticking too much to the pan.

Mine took about an hour and a half to get to this point. They should cook down in 45 minutes. I probably had my heat too low and turned the onions too frequently because I was afraid they’d scorch. 

Once the onions are caramelized and the tomatoes and zucchini have drained it’s time to layer your tart. Don’t begin until everything is in place otherwise your crust will become soggy. Place the caramelized onions in the tart dish.
