Grilled Sweet Potato Planks with Avocado and Tomato Topping

Imagine the smoky aroma of sweet potatoes mingling with the rich, creamy textures of ripe avocados, perfectly complemented by the freshness of sliced tomatoes. This Grilled Sweet Potato Planks with Avocado and Tomato Topping is not just a dish; it’s an experience. Combining the wholesome goodness of fresh produce with the tantalizing taste of a grill, this recipe balances simplicity and sophistication. Perfect for a refreshing dinner or a light weekend lunch, these grilled potato planks come alive with a touch of spices and citrus.
Key to this dish is the selection of ingredients and the technique used to bring out the vibrant flavors. Look for firm, orange-fleshed sweet potatoes and choose ripe Hass avocados that yield slightly to pressure when squeezed. To achieve that delicious char on the sweet potatoes, ensure your grill is preheated adequately. This grilling not only imparts alluring grill marks but also enhances the natural sweetness and tenderness of the potatoes.
Preparation begins with slicing the potato into thick, even planks to ensure they cook evenly. Lightly coat them with a cooking spray, infused with spicy steak seasoning, adding an unexpected depth to the dish. This step is crucial for those delicate flavors to adhere and chicanes in taste that every bite promises. Pay special attention while grilling by flipping occasionally—this prevents over-charring and ensures the perfect texture.
Ingredients
- 1 large sweet potato: Provides a healthy, fibrous base with natural sweetness
- Cooking spray: Helps with even seasoning distribution and prevents sticking
- 1 teaspoon spicy steak seasoning, divided: Adds balance and a hint of heat to the dish
- 1 ripe Hass avocado: Lends creaminess and rich texture
- 1 plum tomato: Brings brightness and slight acidity
- 1 lime, for wedges: Refreshes and adds a zesty finish
- 1 teaspoon fresh thyme leaves: Offers a subtle herbal lift

Step-by-Step Instructions
- Preheat your grill or grill pan to medium heat. While it's heating, prepare your ingredients.
- Slice the ends off the large sweet potato, and then cut the potato into ½-inch-thick planks to ensure even cooking.
- Coat sweet potato planks with cooking spray, making sure to cover all sides evenly. Sprinkle ½ teaspoon of the spicy steak seasoning over them to infuse flavor.
- Grill the sweet potatoes for about 8 to 10 minutes, flipping occasionally. You’re looking for defined grill marks and softened, yet firm, potatoes. Pay attention to avoid overcooking.
- Meanwhile, halve the ripe avocado, remove the pit, and scoop out the flesh. Slice it thinly to easily layer on top of the potatoes.
- Slice the plum tomato thinly, and prepare lime wedges by cutting the lime.
- Once the potatoes are ready, remove them from the grill and arrange on a serving plate.
- Top each potato plank with sliced avocado and tomato, then sprinkle on fresh thyme leaves and the remaining spicy steak seasoning.
- Serve with lime wedges for that final citrus zing. Enjoy immediately to savor each fresh, vibrant flavor!

Tips for Troubleshooting if Something Goes Wrong with the Recipe
- Too thick? Add a bit of liquid, such as olive oil, and gently stir for a smoother consistency.
- Too spicy? Balance it out with a spoonful of Greek yogurt or add more avocado for additional creaminess.
- Difficult to flip? Ensure the grill is adequately preheated and use a spatula to gently lift without tearing.
- Not tender enough? Return to the grill for a few more minutes, checking texture after each minute to avoid overcooking.
Ideas for Pairing with the Recipe
- Side dishes: A crisp, fresh garden salad with a lemon vinaigrette complements the smoky, creamy flavors perfectly.
- Drinks: Try a light white wine, like Pinot Grigio, or a refreshing non-alcoholic iced tea with a hint of mint to enhance the meal.
- Desserts or garnishes: Finish with a fruit salad of citrus and berries for a refreshing, sweet conclusion.
How to Store Properly
- Refrigeration: Store leftovers in an airtight container for up to two days to retain freshness.
- Freezing: Not recommended as the avocado texture changes; however, sweet potatoes can be frozen before adding toppings.
- Ahead of time: Prepare each element in advance and assemble right before serving for the best taste and texture.
FAQs
- Can I use another type of potato? Certainly! Try using white or red potatoes for a different texture and flavor profile.
- What if I don't have a grill? A grill pan or even an oven with high broil settings can replicate a similar effect.
- How can I tell if the avocado is ripe? It should yield slightly to pressure when gently squeezed, but not be overly soft.
- Is there a substitute for fresh thyme? Yes, dried thyme works as well; use about half the amount as dried herbs are more potent in flavor.
