Asparagus Squash Gratin

Teresa Ambra

Gluten Free Living – 2014

Asparagus Squash Gratin is a lovely casserole that was born out of necessity. A few weeks ago when the ice storms blew through North Texas and everyone was without power for days, we had some friends over for a hot meal because they were without power and tired of eating cold food.

Follow Me On Instagram!

I made up Tortilla Casserole which was a new recipe I had never tried before, and my delicious Mandarin Spinach Salad. I hadn’t grocery shopped in awhile so I had to go with what was on hand because I wasn’t going to get out on icy roads. It was a crazy time.

We would have had them stay with us but we were having septic problems so I could offer them a hot meal but not a hot shower! Thankfully, their power is restored and our septic has been pumped and is back to normal.

As I was preparing the meal I felt like we should have something else on the menu so I checked out my garage freezers to see if I could throw something together. I found a package of frozen yellow squash, frozen zucchini, and frozen asparagus spears and decided to start with that. I added some red onion and then made a delicious cream sauce with fontina cheese. The taste was absolutely amazing. If you have other garden veggies you want to use up (carrots, mushrooms, celery, leeks, bell peppers all come to mind) then this would be a great recipe to use those in as well.

I have to admit Fontina cheese is becoming my cheese of choice for au gratin recipes. It has such a terrific flavor. I buy it almost whenever I see it in the store and freeze it for whenever I need it. It sure came in handy for making this recipe.

I didn’t have any fresh veggies on hand because I hadn’t wanted to get out on the roads for several days (yes, I’m a chicken when it comes to driving on icy roads even though we lived in New England for several years and I “learned” how to drive on ice and snow–sort of.) So, I was grateful for having stocked my freezer with some frozen veggies that needed to be used up anyway and had ingredients on hand to make a cheese sauce.

I really loved the flavors of Asparagus Squash Gratin and will use this sauce again with other veggies. If you’re looking for ways to use up garden produce like squash, zucchini, carrots, or asparagus then I can certainly recommend this casserole. I made this recipe gluten free but regular flour will work as well. Asparagus Squash Gratin was delectable. I really loved the way this casserole turned out and if you give it a try, I think you will, too.

When I initially posted this recipe in January 2014, I had my Canon camera on hand, but because I was making this casserole so late at night I used my regular iPhone. The pictures were blurry and certainly not as pleasing as I would have liked. I recently remade this recipe (December 2016) for a Sunday school class Christmas party. I added carrots and used all fresh veggies this time. I couldn’t find plain fontina cheese so I used a six-cheese Italian blend instead. It was mouthwatering.

Several of the folks at the party loved the combination of veggies and the flavors of the sauce. This casserole is a great one to serve company. I highly recommend it for holiday meals, too. It’s so hearty and filling you can easily make this for a meatless Monday. It’s such a versatile recipe and certainly one you can make in the summer if you have a lot of garden produce on hand. The basil-thyme cream sauce is tasty and delightful. Give it a try and you’ll see what I mean.

Here’s what I did.

I used these ingredients. I do not recommend using Pamela’s gluten free baking mixes as the texture and flavor is off. But it was the only product readily available at the time. Bob’s Red Mill or even Walmart’s Great Value brand of gluten free flour is better.

In a large mixing bowl combine fresh asparagus, yellow squash, zucchini and partially cooked carrots. Add diced red onions and garlic.

I usually add about 1/8 cup at a time, whisking after each addition and continue to work in all of the cream.

Notes
The sauce in the pictures for this recipe is twice what is included here in the recipe, I have decreased the sauce ingredients by half for this recipe card because it was more than necessary for this ratio of veggies.[br][br]If you want to add an additional 4-6 cups of veggies than the original sauce will be fine and you can double the sauce ingredients.

    […] Asparagus & Squash Gratin […]

      Can the Asparagus & zucchini Gratin be made & cooked the night before & just warmed before next days dinner?

      1. Teresa

        December 24, 2020 at 5:12 am

        Hi, Aggie. Yes, you can certainly do that. Or you can make it up to the point where you bake it. Refrigerate it, then bake it like before. You will probably have to add additional time if you have multiple things in the oven or if the casserole is cold.
