Recipe FAQ

Can I use fresh tuna instead of canned?

Fresh tuna can work, but canned tuna is preferred for this soup as it holds its shape better and absorbs the flavors. If using fresh, grill or sear it separately and add it at the end to prevent overcooking.

How long does this soup keep in the refrigerator?

Store cooled soup in an airtight container for up to 3 days. The flavors often improve overnight. Reheat gently over medium-low heat, adding a splash of broth if needed.

Can I freeze this soup?

Yes, freeze for up to 3 months. The tuna may become slightly softer after freezing, but the flavor remains excellent. Thaw overnight in the refrigerator before reheating.

What vegetables can I add to make it heartier?

Consider adding diced zucchini, spinach, or bell peppers during the simmering stage. Small pasta shapes like ditalini or orzo also work well for a more substantial bowl.

Is this soup spicy?

The red pepper flakes are optional and provide only mild heat. For more spice, increase the amount or add a pinch of cayenne pepper. The soup remains mild and family-friendly without them.

Can I use tuna in water instead of oil?

Yes, simply drain the water-packed tuna well. You may want to add an extra teaspoon of olive oil when sautéing the vegetables to maintain the rich mouthfeel.
