Ingredients

1 watermelon large
2 tablespoons olive oil divided
2 cloves garlic crushed
¼ teaspoon salt
¼ teaspoon black pepper ground
1 tablespoon soy sauce or tamari or coconut aminos
1/2 teaspoon liquid smoke
1 teaspoon brown or red miso paste
Balsamic glaze for serving
Sesame seeds optional, for garnish

Instructions

Prepare the Watermelon

Slice the watermelon in half, then into round slices about 1 inch thick. Cut off the rind and shape into rectangles to make at least 6 "steaks."
1 watermelon

Remove Excess Moisture

Use paper towels to pat the watermelon pieces dry. Removing moisture helps them sear better in the pan.

Make the Marinade

In a small bowl, whisk together 1 tablespoon olive oil, crushed garlic, salt, pepper, soy sauce, and miso paste.
2 tablespoons olive oil, 2 cloves garlic, ¼ teaspoon salt, ¼ teaspoon black pepper, 1 tablespoon soy sauce, 1 teaspoon brown or red miso paste, 1/2 teaspoon liquid smoke

Marinate the Watermelon

Brush the marinade over both sides of each watermelon steak.

Cook the Steaks

Heat the remaining 1 tablespoon olive oil in a large skillet over medium heat.
Add the watermelon steaks to the pan. Cook for 5 minutes on each side.
Uncover, increase the heat to medium-high, and cook for 2 more minutes on each side, until browned.

Serve

Drizzle with balsamic glaze to resemble grill marks as a garnish with sesame seeds or crumbled feta or shaved parmesan (dairy or vegan).

Notes

Important Prep Tips Before Starting the Recipe:

Watermelon slices should be cold and well-dried for the best sear.
A large non-stick or cast-iron skillet works best for even browning.
Use a basting brush for even marinade coverage and avoid oversaturating the steaks.

Common Mistakes When Making This Recipe:

Skipping the drying step. Too much moisture keeps the watermelon from browning.
Forgetting to preheat the pan. A properly heated skillet is key for that golden crust.
Cooking on heat that’s too high from the start. You need a slow start to warm it through before searing.

Storage and Reheating Instructions

Store leftovers in an airtight container in the refrigerator and enjoy within 1–2 days for best texture. Avoid stacking slices when storing. Use parchment between layers to prevent sogginess.
Not ideal for freezing due to high water content.
For reheating, a non-stick skillet over low heat works best to preserve the crust. Add a splash of soy sauce if it seems dry.
