This 4-ingredient slow cooker Independence Day salmon is the kind of easy, dump-and-go recipe that busy families secretly rely on for holidays and weeknights alike. Using un-drained canned red sockeye salmon means you get all that rich flavor and healthy protein without any fuss, and everything goes straight into the crock pot—no pre-cooking, no fancy steps. The result is a tender, savory salmon you can scoop right out of the slow cooker, perfect for a laid-back Independence Day spread when you want something a little special but still simple enough to pull off between parades, fireworks, and kids running in and out of the house.
Serve this slow cooker salmon spooned over fluffy white rice, buttered egg noodles, or toasted hamburger buns for easy salmon sandwiches. Add a side of corn on the cob, coleslaw, or a simple green salad to keep things light and summery. A squeeze of fresh lemon, a sprinkle of chopped dill or parsley, and some pickles or sliced tomatoes on the side make it feel like a complete holiday meal without a lot of extra work.
4-Ingredient Slow Cooker Independence Day SalmonServings: 4
Ingredients
2 (14.75-ounce) cans red sockeye salmon, NOT drained
1/2 cup ketchup
1/4 cup brown sugar, packed
1 tablespoon yellow mustard
Directions
Open the canned red sockeye salmon and pour it, including all the liquid, directly into the bottom of a slow cooker. Gently break up the salmon with a fork into large chunks, removing any obvious large bones or skin pieces if your family prefers, but it’s fine to leave the softer bones in for extra calcium.
In a small bowl, whisk together the ketchup, brown sugar, and yellow mustard until smooth and well combined.
Pour the ketchup mixture evenly over the salmon in the slow cooker. Use a spoon to lightly fold the sauce through the salmon so everything is coated, but don’t over-stir—you want some nice big flakes of salmon to stay intact.
Cover the slow cooker with the lid and cook on LOW for 2 to 3 hours, or on HIGH for about 1 to 1 1/2 hours, until the mixture is hot and bubbly and the flavors have blended. Since the salmon is already fully cooked, you’re mainly heating and letting the sauce soak in.
Once heated through, gently stir again, taste, and adjust the seasoning if you like by adding a pinch of salt, a little more mustard, or a spoonful of brown sugar for extra sweetness.
Turn the slow cooker to WARM for serving, and scoop the salmon directly from the crock pot onto plates, over rice or noodles, or onto buns for sandwiches.
Variations & Tips
For picky eaters, you can mash the salmon more thoroughly so there are fewer visible chunks and mix in an extra tablespoon or two of ketchup to make it a bit sweeter and more familiar, almost like a sloppy-joe-style filling. If your family likes a little kick, stir in 1 to 2 teaspoons of hot sauce or a pinch of red pepper flakes with the ketchup mixture. For a slightly tangier version, swap the yellow mustard for Dijon or add a tablespoon of apple cider vinegar. You can also stir in 1/2 cup of finely chopped onion or bell pepper before cooking for extra texture and flavor, but that will add to the ingredient list. To keep it feeling extra festive for Independence Day, serve the salmon on toasted buns with sliced pickles and a bit of shredded cheese on top.
Food safety tips: Canned salmon is already fully cooked, but always check the can for any damage, bulging, or rust before using, and never use cans that are dented along the seams or leaking. Store unopened cans in a cool, dry pantry. Once you open the cans and add the salmon to the slow cooker, keep everything refrigerated if you’re not starting the cooking process right away, and do not leave the opened salmon sitting out at room temperature for more than 2 hours (or 1 hour if it’s very hot in the kitchen). When cooking, make sure the mixture is heated thoroughly and kept at a safe temperature; once the meal is over, refrigerate leftovers within 2 hours in a shallow, covered container and use within 3 days. Reheat leftovers until steaming hot before serving.
