A Summery Dream – Salad with Chicken and Watermelon

This salad makes a perfect warm-weather dinner: hydrating, ripe watermelon and tender balsamic-glazed chicken layered over crisp romaine. Add crunchy walnuts, a light sprinkle of fresh mint, and tangy marinated red onions for a balanced, refreshing plate.

Only the chicken needs to be cooked, and it simmers in a sticky balsamic reduction while you prepare the rest of the salad. The contrast of sweet watermelon and savory, slightly caramelized chicken is delightful.

The chicken browns quickly and the balsamic reduces to a glaze that clings to the meat. If you like, finish plates with a drizzle of the onion marinade oil or an extra splash of balsamic for added depth.

How to Make Watermelon Chicken Salads

Marinated Red Onions

Step 1: Thinly slice a red onion and toss with olive oil, white wine vinegar, sea salt and dried oregano in a bowl until evenly coated.

Step 2: Let the onions sit at least a couple of hours, or preferably overnight. If the onions remain fully submerged in the marinade they can be kept at room temperature for several days.

Step 1 shows adding the onions to a bowl to marinate, and step 2 shows letting them marinate overnight.

Balsamic Chicken

Step 3: Heat a skillet with avocado oil over medium-high heat. Season the chicken generously with salt and pepper and brown on the first side.

Step 4: Flip the chicken, pour in the balsamic vinegar and reduce the heat to medium-low. Simmer for about 15 minutes, flipping occasionally, until the chicken is cooked through and the balsamic has reduced to a thick, sticky glaze. Add a tablespoon or two of water if the vinegar reduces too quickly to prevent burning.

Assemble the Salads

Step 5: Divide chopped romaine among plates.

Step 6: Top each plate with cubed watermelon, then slice the balsamic chicken and arrange it over the salad.

Step 7: Garnish with chopped walnuts, chopped fresh mint, and a generous spoonful of the marinated red onions. Optionally drizzle a little of the onion oil or extra balsamic over the finished salad.

Frequently Asked Questions

Is this Watermelon Chicken Salad Whole30 compliant?

Yes — as written the recipe is Whole30 friendly. Avoid store-bought balsamic glazes that often contain added sugar. The marinated onions, walnuts and mint add plenty of flavor so the salad works well without cheese.

Do cheese and watermelon pair well?

Many watermelon salads include feta, which is a classic pairing. If you enjoy that combination, scatter feta over the salad with the walnuts and mint.

How to store leftovers

For meal prep, store cooked balsamic chicken, chopped romaine, cubed watermelon and marinated onions in separate containers. Reheat the chicken briefly in a skillet and assemble the salad just before serving to keep textures fresh.
