Southwest Tuna Salad with Black Beans

Southwest Tuna Salad with Black Beans

Amanda McKillop
Inspired by the bright, smoky flavors of the American Southwest, this tuna salad marries pantry staples with market-fresh crunch. Roasted corn, chipotle-lime dressing, and crisp tortilla strips deliver contrast in every bite—creamy, zesty, and lightly smoky. High-protein tuna and hearty black beans make it satisfying without feeling heavy.

Equipment

  • Oven
  • Sheet pan
  • Parchment paper
  • Skillet
  • Mortar and pestle or spice grinder
  • Mixing bowls
  • Whisk
  • Colander
  • Chef's Knife
  • Cutting board
  • Measuring cups and spoons
  • Microplane or fine grater

Ingredients
 
 

For the Roast & Toast:

  • 1 ½ cups corn kernels fresh or frozen, thawed
  • 2 tsp neutral oil for corn
  • ½ tsp chili powder
  • ¼ tsp kosher salt for corn
  • 2 pieces corn tortillas 6-inch, cut into thin strips
  • 2 tsp neutral oil for tortilla strips
  • 1 pinch kosher salt for tortilla strips
  • 1 tsp cumin seeds to toast and crush

For the Dressing:

  • 3 tbsp fresh lime juice about 2 limes
  • 3 tbsp extra-virgin olive oil
  • 1 tsp honey
  • 1 clove garlic small, grated
  • 1 tsp chipotle in adobo minced, with a little sauce
  • ½ tsp kosher salt for dressing
  • ¼ tsp freshly ground black pepper for dressing

For the Salad:

  • 2 cans tuna in water 5-oz cans, drained and flaked
  • 1 can black beans 15-oz, drained and rinsed
  • 1 medium red bell pepper small dice
  • 1 cup cherry tomatoes halved
  • ¼ cup red onion finely diced
  • 1 small jalapeño seeded and minced
  • 4 cups romaine lettuce thinly sliced
  • ⅓ cup cilantro coarsely chopped, tender stems ok
  • 1 large avocado diced
  • 1 tsp lime zest finely grated
  • ⅓ cup Cotija cheese crumbled, optional

Instructions
 

  • Preheat and Prepare the Pan: Preheat the oven to 425°F / 220°C. Line a sheet pan with parchment for easy cleanup.
  • Roast Corn and Bake Tortilla Strips: In a bowl, toss 1 1/2 cups corn with 2 tsp neutral oil, 1/2 tsp chili powder, and 1/4 tsp kosher salt. Spread on half the pan. In the same bowl, coat the tortilla strips with 2 tsp neutral oil and a pinch of salt; spread on the other half. Bake until the corn is blistered and the strips are crisp, 10–12 minutes, stirring the corn once halfway. Cool on the pan for 5 minutes to set the crunch.
  • Toast and Crush the Cumin: While the pan is in the oven, warm a dry skillet over medium heat. Add 1 tsp cumin seeds and toast, stirring, until fragrant, about 2 minutes. Transfer to a mortar and crush to a coarse powder (or pulse in a spice grinder).
  • Whisk the Chipotle–Lime Dressing: In a medium bowl, whisk together 3 tbsp lime juice, 3 tbsp olive oil, 1 tsp honey, grated garlic, 1 tsp minced chipotle in adobo, and the crushed cumin. Season with 1/2 tsp kosher salt and 1/4 tsp black pepper, then whisk until fully emulsified and glossy, 20–30 seconds.
  • Prep the Proteins and Veg: Drain and flake the tuna. Rinse and drain the black beans thoroughly in a colander. Small-dice the red bell pepper; halve the cherry tomatoes; finely dice the red onion; mince the jalapeño; slice the romaine; chop the cilantro; and dice the avocado last to minimize browning.
  • Build the Salad: In a large mixing bowl, combine the tuna, black beans, bell pepper, tomatoes, red onion, jalapeño, romaine, and the roasted corn. Pour in the dressing and fold gently with a spatula until evenly coated and glossy, 30–45 seconds.
  • Finish and Season: Fold in the avocado and lime zest just before serving. Taste and adjust with a pinch more salt or a squeeze of lime if needed. Plate and top with the crisp tortilla strips and Cotija.
  • Serve and Store: Serve slightly cool or lightly chilled. For meal prep, refrigerate in a covered container at or below 40°F / 4°C and enjoy within 2 days; store tortilla strips separately to keep them crisp.

Notes

Chef’s Tips:

  • Tuna Texture: For extra richness, use one can of oil-packed tuna and one can of water-packed, draining both well. Flake gently to keep meaty pieces intact.
  • Heat Control: Increase chipotle to 2 tsp for a spicier profile, or use 1/4 tsp smoked paprika for a milder, smoke-forward vibe.
  • Crunch Swap: If short on time, substitute 2/3 cup crushed tortilla chips for the baked strips—add just before serving.
  • Onion Finesse: If your red onion tastes sharp, rinse the dice under cold water for 20 seconds, then pat dry for a sweeter crunch.
  • Creamy Variation: Stir in 2 tbsp Greek yogurt to the dressing for a lightly creamy, tangy finish without overwhelming the lime.
