If you’re looking for an easy, healthy side dish, Blackstone Zucchini and Squash is a great choice. With simple ingredients and minimal prep, this recipe becomes a family favorite fast.

Cooking zucchini and yellow squash on a Blackstone griddle brings out a delicious, slightly caramelized flavor that steamed vegetables can’t match. The griddle works especially well for families because it cooks evenly and quickly.
Before using the griddle, make sure it’s clean and preheated. This method is simple enough to adapt with different seasonings or to pair with a variety of mains.
How to Cut Zucchini for Grilling
Choose a cut based on texture and presentation:
- Cut in Rounds: Slice zucchini into 1/4-inch rounds for quick, even cooking.
- Diagonal Cut: Cut at an angle for larger slices with more surface area for browning.
- Planks: Slice lengthwise into thicker planks if you prefer a steak-like piece.
Ingredients

- 2 zucchinis

Different Seasonings to Use
This recipe is a flexible base—try paprika, creole seasoning, or steak seasoning for a bolder profile. Fresh herbs, a splash of balsamic vinegar, or a pinch of red pepper flakes also add delicious variety.
How to Make Zucchini on the Blackstone
Step 1 — Prepare the griddle: Preheat your Blackstone over medium-high heat, about 400°F.
Step 2 — Slice the vegetables: Cut the zucchini and yellow squash into thin slices, roughly 1/4 inch thick.
Step 3 — Add oil to the griddle: Spread the avocado oil across the cooking surface with a spatula. Olive oil works well too.
Step 4 — Cook in a single layer: Arrange the slices in a single layer on the oiled griddle and season with garlic salt and black pepper.

Step 5 — Sear and flip: Cook for 2–3 minutes, then flip and cook a few more minutes until the vegetables reach your preferred tenderness and have a light golden color.
Step 6 — Serve: Plate warm and adjust seasoning with additional salt and pepper if desired.
How Long to Cook Zucchini on Blackstone
Cook over medium heat about 2–3 minutes per side depending on thickness. Thinner slices will cook faster; thicker planks may take a minute or two longer. Remove when they have a nice sear and are tender but not mushy.

How to Store Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 5 days. Reheat gently on the griddle or in a skillet to refresh the texture.
