Here's everything for your keto vegetarian grilled zucchini with spinach avocado pesto. Simple stuff, big payoff.
For the Grilled Zucchini
| Ingredient | Amount |
|---|---|
| Medium zucchini | 3–4 (sliced lengthwise) |
| Olive oil | 2 tablespoons |
| Garlic powder | ½ teaspoon |
| Salt & black pepper | To taste |
| Red pepper flakes | Optional, for heat |
For the Spinach Avocado Pesto
| Ingredient | Amount |
|---|---|
| Fresh baby spinach | 2 cups packed |
| Ripe avocado | 1 large |
| Fresh basil leaves | ½ cup |
| Garlic cloves | 2 |
| Lemon juice | 2 tablespoons |
| Olive oil | 3 tablespoons |
| Pine nuts (or walnuts) | ¼ cup |
| Salt & pepper | To taste |

How to Make Keto Vegetarian Grilled Zucchini with Spinach Avocado Pesto
Step 1: Make the Spinach Avocado Pesto First
Do yourself a favor and start with the pesto. It gets better as it sits.
- Add spinach, basil, garlic, and pine nuts to a blender or food processor.
- Pulse a few times until roughly chopped.
- Add avocado, lemon juice, olive oil, salt, and pepper.
- Blend until smooth and creamy. Taste and adjust seasoning.
- If it's too thick, add a splash of water or extra olive oil.
That's it. The whole thing takes about 5 minutes. Future you will thank you.
Step 2: Prep and Grill the Zucchini
- Slice zucchini lengthwise into ¼-inch planks — not too thin or they'll fall apart on the grill.
- Brush both sides with olive oil and season with garlic powder, salt, pepper, and red pepper flakes if using.
- Heat a grill pan (or outdoor grill) over medium-high heat until hot.
- Grill zucchini for 3–4 minutes per side until you get those gorgeous char marks and the slices are just tender.
Fair warning: Don't walk away. Zucchini goes from perfectly charred to soggy pretty quickly. Stay close.
Step 3: Plate and Serve
Arrange the grilled zucchini planks on a serving platter. Spoon the spinach avocado pesto generously over the top — or serve it on the side for dipping. Finish with:
- 🌿 Fresh basil leaves
- 🍋 A squeeze of lemon
- 🧀 Extra Parmesan shavings (skip for dairy-free)
- 🌶️ A pinch of red pepper flakes
Your weeknight just got better. Crowd-pleaser alert: this dish disappears fast.

Tips, Swaps & Serving Ideas
Make it your own:
- No grill pan? A regular skillet works — you just won't get the char marks. No judgment here.
- Nut-free? Swap pine nuts for pumpkin seeds in the pesto.
- Add protein: Top with a fried egg or crumbled feta for extra staying power.
- Meal prep magic: The pesto keeps in the fridge for up to 3 days. Press plastic wrap directly on the surface to prevent browning.
- Serve it as: a side dish, light lunch, or appetizer with low-carb crackers.
