Pour un-drained pouches of chunks of light tuna in the slow cooker and 3 everyday pantry staples to create a dish so incredible your whole family will be asking for seconds!

This 4-ingredient slow cooker Independence Day tuna is the kind of set-it-and-forget-it meal I lean on when the holiday weekend is packed with parades, fireworks, and kids running through sprinklers. You literally pour un-drained pouches of chunks of light tuna into the slow cooker, add three everyday pantry staples, and let the slow cooker do the work. The result is a cozy, creamy, all-American-style tuna dish that tastes like a cross between tuna casserole and a warm tuna melt filling—perfect for scooping over toast, rice, or pasta when you want something comforting but don’t have the time (or energy) for a fussy recipe.

Serve this slow cooker tuna spooned over buttered toast, toasted hamburger buns, or cooked egg noodles for a retro, diner-style meal. It’s also great piled onto crackers as a warm dip for a casual Independence Day spread. Add a simple green salad, coleslaw, or sliced tomatoes and cucumbers on the side to keep things fresh. If you’re feeding a crowd, keep the tuna on the “warm” setting and set out a little DIY bar with buns, shredded lettuce, and pickles so everyone can build their own sandwiches.

Servings: 4

4 (2.6–3 oz) pouches chunks of light tuna in water, un-drained

Place the un-drained pouches of chunks of light tuna in the bottom of a 3- to 4-quart slow cooker. Squeeze or scoop out every bit of tuna and its liquid so it forms an even layer on the bottom (this liquid helps keep everything moist).

Use a fork to gently break up and spread the tuna into an even layer, but don’t worry about making it perfect. You just want to avoid large clumps so it heats evenly.

In a medium bowl, stir together the condensed cream of mushroom soup and mayonnaise until smooth and well combined.

Pour the soup and mayonnaise mixture evenly over the tuna in the slow cooker. Do not stir; leaving the tuna at the bottom lets it soak up the flavors and keeps the texture tender as it cooks.

Sprinkle 3/4 cup of the shredded cheddar cheese evenly over the top of the soup layer, reserving the remaining 1/4 cup for later.

Cover the slow cooker with the lid and cook on LOW for 2 to 3 hours, or on HIGH for 1 to 1 1/2 hours, until the mixture is hot and bubbly around the edges.

Once hot and bubbly, gently stir everything together right in the slow cooker until the tuna, soup mixture, and melted cheese are well combined and creamy.

Sprinkle the remaining 1/4 cup shredded cheddar cheese over the top. Cover again and let it sit on LOW (or “warm”) for about 5 to 10 minutes, just until the cheese on top is melted.

Taste and adjust seasoning if needed with a pinch of salt and pepper, then serve the tuna hot over toast, buns, noodles, or rice.

For a lighter version, use light mayonnaise and a reduced-fat condensed soup. You can also swap cream of mushroom soup for cream of celery or cream of chicken, depending on what’s in your pantry. If your family loves a little kick, stir in 1 to 2 teaspoons of Dijon or yellow mustard after cooking, or add a pinch of red pepper flakes. For extra veggies, fold in 1 cup of well-drained frozen peas or mixed vegetables during the last 30 minutes of cooking so they warm through without getting mushy. If you’d like a more casserole-style dish, cook 8 ounces of egg noodles separately, then gently stir them into the slow cooker right before serving, thinning with a splash of milk if needed. Food safety tips: Use shelf-stable tuna pouches that are within their expiration date and unopened before use. Keep the tuna mixture above 140°F if holding on the “warm” setting and do not leave it out at room temperature for more than 2 hours (1 hour if it’s very hot outside at a cookout). Refrigerate leftovers in a shallow container within 2 hours and eat within 3 to 4 days, reheating until steaming hot before serving.
