Grilled Zucchini Mini-Tostadas with Refried Beans [found on KalynsKitchen.com]

I realize August is the month with a special day to celebrate zucchini, but everyone who’s grown zucchini in a garden knows that in September and October, when you’re not focused on the garden so much, you can find giant zucchinis springing up overnight.  I have a few friends and relatives who’ve been giving me giant zucchinis lately, so I’m having fun dreaming up new ways to use them.

I used a big zucchini about 3 inches across to make these Grilled Zucchini Mini Tostadas with Refried Beans.  This was easy to make and if you have kids it would be a fun meal to get the kids to help assemble.  If you want to make this and you don’t have giant zucchini, I would just slice smaller zucchini the other way and make oblong-shaped tostadas; enjoy!

I ate three of these for a tasty meatless lunch, and they’d also make a nice dinner if you served them with something else on the side.

I use my beloved Mandoline (affiliate link) with a 7mm blade to get even thin slices, but you can slice by hand if you don’t have a mandoline. (I cut 12 slices, but I could have easily eaten four of these for lunch so I’d suggest cutting more if you have a big enough zucchini.) Put the refried beans and diced green chiles into a pan with a little water, and let it simmer on low and thicken while you prep other ingredients.  Spray grill with nonstick spray and preheat to high.  (You could make these with a broiler as well if you have a wire rack to put the zucchini slices on.) I simmered the bean mixture about 20 minutes, scraping the bottom and sides of the pan every few minutes.  Let the mixture cool for about 5 minutes before you put it on the zucchini slices.

Lay the zucchini slices out on a cookie sheet and spray each side with a little olive oil. (I use the Misto Olive Oil Sprayer. Affiliate link.) Sprinkle both sides with a pinch of Kalyn’s Taco Seasoning (or your favorite purchased taco seasoning.) Lay the slices on the hot grill and cook about 6-7 minutes on the first side. Then turn and cook 5-7 minutes on the second side, or until the zucchini is cooked and slightly browned.

While the zucchini cooks get some salsa, grated Three Cheese Mexican Blend (or your favorite low-fat cheese), and sliced olives. When the zucchini is done, lay it out on the cookie sheet to assemble the mini tostadas. Top each zucchini slice with 1 tablespoon of the refried bean mixture. Then use a fork (or your clean fingers) to spread out the beans so they come almost to the edge of the zucchini slices.

Top the beans with 1 teaspoon of salsa. Give each mini tostada a generous pinch of cheese.  (And if you can do this without getting the cheese all over, you’re doing better than me!) Top each mini tostada with some sliced olives and eat right away.  You can use other toppings like sour cream, avocado, diced tomato, or lettuce if you’d like.

Grilled Zucchini Mini Tostadas with Refried Beans

Grilled Zucchini Mini Tostadas with Refried Beans are a fun way to use zucchini.


  • 1 can (16 oz.) refried beans (or about 1 cup homemade refried beans)
  • 1 can (4 oz.) diced green chiles (Anaheim chiles, not jalapenos, unless you want it really spicy)
  • 1/4 cup water
  • 1 giant zucchini, cut into about 16 slices, each about 3/8 inch thick and about 3 inches across
  • olive oil, for spraying zucchini slices
  • Kalyn’s Taco Seasoning, or your favorite store-bought brand, for sprinkling zucchini slices
  • about 1/3 cup salsa (I used Pace Medium Picante Sauce)
  • about 1 cup grated cheese (I used Kirklands Three Cheese Mexican Blend, which is a blend of reduced-fat cheese)
  • about 1/4 cup sliced olives
  • optional toppings like sour cream, diced tomatoes, diced avocado, or lettuce can also be used


  1. Spray a small saucepan with nonstick spray and add the can of refried beans, can of diced green chiles, and 1/4 cup water.  Stir together, then let the mixture simmer over low heat about 15-20 minutes, or until it’s thickened and the beans are well-flavored from the diced green chiles.  (The beans will stick to the pan, I used a turner to scrape the sides and the bottom every few minutes.)
  2. Spray a clean grill with nonstick grill spray and heat to high.
  3. While the beans are simmering, wash the zucchini, cut off both ends, then use a Mandoline (affiliate link) or a sharp knife to cut the zucchini into thin slices about 3/8 inch thick.  (I used my mandoline with a 7mm blade, which was just perfect.  In the photos I only made 12 slices, but I had extra beans left over and I could have easily eaten four of these for a light lunch, so I would make at least 16 slices if you can get that many.)
  4. Lay the zucchini slices out on a large cookie sheet (or two) and spray each side of the zucchini with olive oil and sprinkle with a pinch of Kalyn’s Taco Seasoning.
  5. Put zucchini slices on the hot grill and grill about 6-7 minutes on the first side, then turn and grill 5-7 minutes on the second side, or until the slices are cooked and slightly browned.
  6. While zucchini cooks, prepare the salsa, grated cheese, black olives, and any other toppings you’re using.
  7. Let the beans cool a few minutes before you assemble the tostadas.
  8. When zucchini is done, lay the slices back on the cookie sheet to assemble the tostadas.
  9. Put about 1 tablespoon of the refried bean mixture on each zucchini slice; then spread the beans with a fork (or your clean fingers.)  Spread about a teaspoon of salsa over the bean mixture.  Sprinkle each tostada with a generous pinch of grated cheese and add a few slices of olive to each.  Eat right away.


Here is the recipe for Kalyn’s Taco Seasoning.

These don’t keep well, but you can prepare all the beans and cut all the zucchini when you first make them.  Then just grill as many zucchini slices as you will eat at one sitting, keeping the rest in the fridge in a Ziploc bag to cook later.  Beans can be microwaved for a minute or two if they’ve been in the fridge.

  5. Hi Wanda, glad you like the idea. And I think this would be lots of fun to make with the grandkids!

  6. What a treat! Wonderful for my new preference for small plate food.

  10. Great idea, Kalyn! I loved your zucchini slice pizza recipe, too. Might as well take advantage of the larger zucchini's girth. 😉


  11. Joanne, they would definitely be fun for appetizers.

    Lydia, the kids would love sprinkling on the cheese, and you're right, they'd probably be even messier than I was!

  12. These look like fun! I can imagine having my grandkids help with the assembly, and then, of course, there would be cheese everywhere!

  13. The zucchini love continues on! THese would make for the perfect little appetizers!
