There are days when supper needs to be simple, plain and dependable, and this 5-ingredient slow cooker tilapia fits that kind of evening just right. Using a solid frozen block of tilapia fillets saves fuss and gets a humble fish supper on the table with very little tending, something any busy household can appreciate. It is the sort of practical recipe that feels right at home in a Midwestern kitchen, where making the most of what is in the freezer has always been part of good cooking.

This tender tilapia is lovely served over hot rice, buttered noodles, or a pile of mashed potatoes to catch every bit of the savory broth. A side of green beans, steamed broccoli, or simple corn makes it a complete meal, and a wedge of lemon or a sprinkle of parsley brightens the whole plate nicely.

Ingredients

1 solid frozen block tilapia fillets, about 2 pounds

1 packet ranch seasoning mix, about 1 ounce
1/2 cup unsalted butter, melted
1 lemon, sliced
1/4 cup water

Directions

1. Place the solid frozen block of tilapia fillets in the bottom of the slow cooker.

2. Pour the melted butter and water over the fish, then sprinkle the ranch seasoning evenly across the top.

3. Lay the lemon slices over the seasoned fish, cover, and cook on low for 2 1/2 to 3 1/2 hours, or until the fish flakes easily with a fork. If the fillets are especially thick or still stuck together, gently separate them during the last hour of cooking.

4. Spoon some of the cooking juices over the fish before serving, and plate with rice, noodles, or vegetables.

Variations & Tips

Add a little garlic: If you do not mind stretching beyond five ingredients, a teaspoon of garlic powder or 2 minced garlic cloves gives the broth a fuller flavor and pairs beautifully with the lemon and butter.

Watch the cook time: Tilapia is delicate, so it is best to check it early rather than late. Slow cookers can vary a good bit, and overcooked fish may fall apart more than you want, even though it will still taste good.

Make it a fuller meal: This fish is especially handy spooned over rice or mashed potatoes so none of the buttery ranch broth goes to waste. A spoonful of the juices over the side dish makes the plate feel complete.

Try a brighter finish: A squeeze of fresh lemon at the table and a little chopped parsley or dill can wake up the flavors nicely and make the finished dish look extra pretty for supper.
