So this recipe came from one of those “what’s in the cupboard” moments. I found myself faced with a whole mess ‘o veggies in the fridge.
As my brain began to assemble which goes with what, I got to thinking about charred corn and my thoughts turned to our annual visit to the fun farm in the fall for apple pickin’ and the delightful succotash they make in a big cast-iron pot.
This is a variation on a traditional succotash recipe, I've swapped in zucchini in place of the lima beans and it's also vegetarian. And just for giggles, I decided to flavor it with homemade taco seasoning. So there you go.
This is a great summer side dish idea. Serve it at your next barbecue. It’ll blow their minds.

What is succotash?
Native Americans introduced succotash to colonists in New England in the 17th century as a stew, primarily consisting of corn and beans. It quickly became a prevalent side dish in the Northeast. Popularity soon spread to Southern states, where ingredients like salt pork and okra became staple ingredients.

Ingredients you'll need
For the homemade taco seasoning
- Chili powder and smoked paprika: You can adjust the spice quotient here a bit to your personal taste. And if you prefer hot paprika to smoked paprika, go right ahead!
- Cumin and ground coriander: These are perhaps the most classic and quintessential spices in taco seasoning.
- Dried oregano: If you can find Mexican oregano, that is preferable. But "regular" Italian oregano works just fine here
- Granulated garlic and granulated onion: The flavor of granulated garlic and onion is a bit stronger and more vibrant than onion powder and garlic powder. You can sub the powdered versions, just taste to ensure that you've got the right balance.
- Kosher salt: Just a bit, not too much. I do hate when seasoning blends seem to be all salt and drown the beautiful flavor of the spices.
For the succotash
- Fresh corn: White, bi-color, or yellow all work well in this recipe. You can make this with canned corn or frozen, just be sure to drain it well and adjust your cooking times.
- Zucchini: In summer, try to find locally grown zucchini for the sweetest flavor.
- Fingerling potatoes: I like the visually and texturally pleasing round-ness that they add to the dish, but you could use small Yukon Golds or baby red potatoes instead.
- Green pepper, garlic, onion: These three workhorses will make up the aromatics for the succotash.
- Cherry tomatoes: We're just going to throw these in at the end to give them a kiss of heat and let them release some sweetness, but we don't cook them down much at all.
- Avocado, cilantro, Queso Fresco, lime: We'll use these as toppings for the dish to add fresh, bright taco vibes. Can’t find queso fresco? Use mild feta or ricotta salata instead.
- Olive oil: You could also use canola or grapeseed oil here.
How to make succotash

Step 1: Mix together the taco seasoning spices
Just whisk them together in a small bowl.
Step 2: Prep and chop vegetables
The cooking goes quick so you really need to have everything chopped and ready to go.
- Chop garlic finely. Chop onion into a corn-sized dice.
- Slice fingerling potatoes into thin rounds.
- Chop green pepper into a ¼ inch dice.
- Remove corn from cob.
- Chop zucchini into a ¼ inch dice.
- Slice cherry tomatoes in half.
Step 3: Cook the succotash
I like to do this on the grill in one of my Lodge cast-iron skillets, but stove-top will work just fine. Cook over medium to medium-high heat whichever you use.
Allow cast iron pan to heat up, then coat the bottom with oil, allow to heat up as well. Add onions and garlic.
Sweat onions and garlic until they become aromatic, then throw in a little of the homemade taco seasoning and stir. Allow to soften and absorb spices.

Add green pepper and potato, then throw in a little more of the homemade taco seasoning. Stir well. (You might need to add a titch more oil here as those taters tend to suck it all up.)

This is where I close the grill and walk away for a few minutes. Check on this mixture and stir every 3-5 minutes or so until the potatoes begin to cook through.
Add corn and zucchini, then hit it with a little more taco seasoning. Stir well.

I prefer to cook the corn and zucchini only until they are slightly sweet but still a bit al dente. If you like it a little more browned and cooked down, go for it.
Remove pan from heat and add cherry tomatoes.
Give it a quick stir and spoon into serving bowls. I like to use these Lodge Cast Iron mini-servers.
Top with crumbled queso fresco, diced avocado and fresh cilantro.
Serve with a fresh lime wedge on the side for squeezing, and hot sauce if desired.

Succotash tips and substitutions
- The great thing about the homemade taco seasoning recipe is that it really is “to the taste."Not so much on garlic? Use less. Like it spicy? Add more chili powder.
- Speaking of spicy you can replace the green pepper with poblanos.
- Make this succotash with whatever you have on hand. Throw in some lima beans or okra or other vegetables if you are so inclined.
