Chiles and cheese turn mild summer squash into a zesty, satisfying casserole. The jalapenos make this dish quite hot; if you prefer a milder version, use a second can of diced green chiles instead.

Super tasty! I substituted chipotle chiles in adobo sauce for the canned green chiles. Gives it a smokey flavor that is divine. I accidentally used hot Ghost Pepper salsa instead of the mild Abuelita salsa I had meant to use (got the jars mixed up). Pretty hot but wow it is good. Read More

Easy to make and delicious! I made the recipe as instructed just this first time to test and it came out very tasty. It was quick and easy to prepare just chop and combine a few things and let the oven do the work! It was a bit spicy for the more wussy of my guests but I loved it. It used up five medium-small yellow summer squash. I think this concoction could even be thrown into a tortilla and made into a healthy burrito. There seemed to be plenty of cheese and flavor so next time I might try adding a little less on top or substitute light cheese and see how that goes. Pros: Uses up a lot of squash! Great flavor and ease of prep Cons: Takes a long time to bake Read More

Cumin and Chili Powder Kicked it Up! We made this with patty pan squash since our share had an abundance and 3 of those made for a veggie overflow. I love the stir-in flour idea so much easier than having to pan-prep something else. We did halve the recipe to use an 8x8 pan and got 6 hearty servings instead. Made it the night before and viola an easy weeknight meal for the fam. The extra-sharp cheese really made this come together but we also tossed in maybe 1 t. of cumin and half that of chili powder plus a bit of queso fresca we had to use up and got a nice sloppy slice just like our King Ranch chicken. This would be a killer alternative of King Ranch for vegetarians and we may try squash instead of tortillas next time we make that! Shallots and jalapeno replaced the red onions and scallions as garnish because we didn't have them and it came out really cute. Biggest surprise: My kid relished this dish. Pros: Great use of squash and kid friendly Cons: Without added spice might be bland Read More

Great Base Recipe I added black beans chopped tomato and frozen corn to make this more of a meal. I also added spices to the veggies cumin garlic and onion powder chipotle lime and pepper. Along with some flour (I didn't measure it out) I added cornmeal since people found it to be too liquid-y. My dish came out amazing! This is def a keeper recipe! Pros: Great base make it what you want! Cons: None! Read More

Definitely A Keeper This dish was so good. Made it for a church function and everyone loved it. I used 2 cans of green chilies instead of the jalepenos. Next time I will do 1/2 zuchinni and maybe some chicken to make it a full meal. Pros: Healthy Read More

Yummy use for zuchhini! YUM! This will now be my go-to recipe for fresh-from-the-garden zucchini! To try this out for myself first I used one 13oz zucchini 1/8c onion 1/8 cup chopped jarred jalapenos sprinkle of salt (we're not salt fans) about 2 handfuls of fiesta blend shredded cheese (the only cheese we had on hand) enough salsa to cover most of the top and a sprinkle of white whole wheat flour. I didn't have the garnish suggestions so I left those out as well as the can of green chilies. I loved how this came out! (FYI - You want to bake this until the squash is tender but not mushy!) I baked my smaller portion for 20 minutes covered uncovered for 10. I plan to make the full-sized recipe for a family get-together on Sunday. I also can't wait to try all of the reviewers' suggestions for making this a meal - they sound delicious! Pros: Easy delicious Read More

A Complete Meal! This recipe is awesome! To make it a complete meal we added lean ground turkey with a little taco seasoning. It was very delicious and my family couldn't get enough of it. I plan on trying to make-ahead and freeze it for this fall since the only downside is heating up the kitchen with the oven being on for about an hour. Pros: quick easy adaptable very delicious! Cons: just heating up the kitchen. Read More

My new favorite Summer Squash recipe I really loved this dish. I am not a fan of really spicy foods so I did skip the green chiles & jalapenos. I did add some salt-free fiesta lime seasoning for some spicy flavor. Also great without the garnishes. Read More

Simple and delicious! I used about 3 yellow summer squashes and an onion added corn black beans cumin oregano chili powder and used only half the amount of jalapenos. I kept the rest of the recipe the same. I also used a mixture of cheddar and mozzarella cheeses. It's delicious! The beans and corn made this a delicious main dish - and It would yummy to dip chips in if I had them (as another reviewers suggested). Really simple good meal! Pros: EASY!!!! Cons: varied from the recipe for more flavor Read More

Fabuloso squash recipe! This casserole was fantastic! I halved the recipe but kept the salsa the same. My husband and I loved the squash! I have to add that if you use a salsa that is chunky the casserole does not get too wet. I realize though that you may not have as many choices of salsa as I do in San Antonio. Maybe you should try straining some of the liquid off of the salsa first. Pros: Flavor flavor flavor! Cons: NONE! Read More

delicious and super easy to make! I added chicken chorizo to make it a full one-dish meal. yum!!! also agree with the other posters: definitely needs extra salsa. I doubled the salsa which made it a bit too wet. next time I make it I'll try an extra 1/3 cup. Read More

I used 2 T. chopped jalapeno instead of the jarred and added one can of drained black beans. Used a lot of salsa- covered the top! There was a little more juice in the bottom of the cooked pan than I like but I just used a big spoon and took some out (didn't want the squash to get mushy). This was quite delicious- a terrific meatless meal- and we will definitely make this again! Read More

Great way to use all that squash from our CSA! I added one large fresh tomato to the squash mixture to give it more color. Next time I'll try adding black beans--what a great idea. Read More

This is an excellent "go to" recipe for a crowd. It is very tasty and the heat level can be adjusted easily by adding more or less jalapenos and mild or medium salsa. I usually think cassaroles are heavy but this has no cream or oil except the cheese. I used Sargento's Low fat 4 cheese Mexican blend (only 1 cup total) and it was excellent. Read More

I would like to say for the record I have no idea what "summer squash" is. LoL I assumed it was the yellow squash and that's what I used. The flavor was great the texture was not. My husband hated it. He ate it a little of it for dinner and never touched it again. I ate leftovers a few times but then lost interest myself. Read More

Surprisingly good! I used the full amount of jalapenos and WOW that's spicy! I do like spicy foods so I find it tolerable. With the lack of spices in this recipe I thought it would be bland. I think the dish is only as good as the salsa you use since that is where the bulk of flavor is coming from. I added a can of drained/rinsed black beans to up the protein and fiber and make it a main dish. A handful of frozen corn would be a nice addition too. We like to eat this casserole with a side of tortilla chips. It is like a healthy version of nachos! Pros: Easy Cons: Lots of slicing and chopping Read More

Spicy and awesome! I couldn't find the jalapenos in the can so I used a second can of the diced green chiles and added some ground red pepper. I was a little worried to serve it to my husband after a readers comment about the texture but he loved it! Great recipe!!! Pros: Good use of summer squash Cons: None Read More

Yum! We've been inundated with summer squash from our garden and this Tex Mex casserole was a great way to use some of it up! It's cheesy and spicy and super easy to make! I added some chopped up homemade veggie burgers for more flavor. This is a great recipe you can feel good about using to branch out and be creative with. Pros: Easy to make flavor-packed versatile good way to use summer squash! Cons: Could be too spicy for those who don't like much heat Read More
