Tuna Niçoise Casserole

To make a classic salad from the south of France a bit heartier for a weeknight family meal, we've transformed a tuna Niçoise into a stove top couscous casserole.

Serves: 8
Hands-on time: 30 minutes
Total time: 30 minutes


  • 2 cups couscous
  • 8 small red potatoes, cut into halves, or 4 large red potatoes, cut into quarters
  • 2 6-oz pouches or cans unsalted water-packed tuna
  • 1/2 lb frozen green beans, thawed
  • 1/2 cup pitted Kalamata olives, sliced
  • Juice and zest of 1 lemon
  • 1 tbsp Dijon mustard
  • 1 tbsp white onion, finely diced
  • 1 clove garlic, minced
  • 1 tbsp apple cider vinegar
  • 2 tsp extra-virgin olive oil
  • 2 tsp fresh flat-leaf parsley, minced
  • Sea salt and fresh ground black pepper, to taste
  • Olive oil cooking spray


  1. Cook couscous according to package directions.
  2. Over medium-high heat, bring a medium-size pan filled with water to boil. Cook potatoes for 10 minutes; drain. In a large bowl, mix together tuna, green beans, olives and potatoes. Once couscous is cooked, mix it into tuna-vegetable mixture.
  3. In a medium bowl, whisk together lemon juice and zest, Dijon, onion, garlic, vinegar, oil, parsley, salt and pepper. Pour dressing over tuna-couscous mixture.
  4. Heat large nonstick or cast-iron skillet over high heat for 1 minute. Reduce heat to medium-high, mist pan with cooking spray and saute tuna-couscous mixture for about 5 minutes or until thoroughly warmed. Remove from heat and serve immediately.
