This 5-ingredient slow cooker jack mackerel is a budget-friendly, comforting way to turn pantry staples into a warm family meal with almost no fuss. Using un-drained canned jack mackerel helps keep the fish moist and flavorful as it cooks with a simple sauce, and the slow cooker does the work while you get on with the rest of the day. It is the kind of practical supper that fits right into a busy weeknight and still feels hearty enough to serve with pride.
Serve this over hot steamed rice, buttery mashed potatoes, or egg noodles to soak up the savory sauce. A side of green beans, sweet peas, sautéed cabbage, or a simple garden salad rounds things out nicely, and a piece of crusty bread or warm cornbread makes this humble meal feel especially satisfying at the table.
5-Ingredient Slow Cooker Jack Mackerel
Servings: 4
Ingredients
2 cans jack mackerel, un-drained
1 medium onion, thinly sliced
1 cup tomato sauce
2 tablespoons Worcestershire sauce
1 teaspoon black pepper
Directions
1. Lightly coat the inside of the slow cooker crock with nonstick spray if desired for easier cleanup, then add the un-drained canned jack mackerel to the bottom of the slow cooker.
2. Scatter the sliced onion over the fish, then pour the tomato sauce and Worcestershire sauce evenly across the top. Sprinkle with black pepper.
3. Cover and cook on low for 2 to 3 hours, just until the onions are tender and the flavors have blended. Try not to stir too much so the fish stays in nice pieces.
4. Gently spoon the jack mackerel and sauce over rice, mashed potatoes, or noodles, and serve hot.
Variations & Tips
For picky eaters: If your family prefers a smoother sauce, chop the onion very finely so it softens right into the dish. You can also serve the fish over extra rice to mellow the flavor a bit.
Make it heartier: Add sliced bell peppers or a couple of cups of drained sliced potatoes to the slow cooker for a more filling one-pot meal. If you add potatoes, plan on the longer end of the cooking time so they become tender.
Boost the flavor: A pinch of garlic powder, a little smoked paprika, or a dash of hot sauce can add extra depth without making the recipe complicated. Since canned fish can vary in saltiness, taste the sauce before adding any extra salt.
Handle the fish gently: Jack mackerel is tender once heated, so use a large spoon and avoid frequent stirring. That helps you keep larger, nicer pieces for serving.
