Why You'll Love Slow Cooker Garlic Butter Tilapia
Flaky and Tender. Slowly cooking the fish with butter adds moisture to your fish and allows it to cook to the perfect doneness. Your fish is done once it reaches 145 degrees F and will be tender; be careful not to overcook it as it will dry out.
Wonderful Flavors! A great combination of seasoning for fish is garlic, butter, and a little bit of spice and acid. In this recipe, we use chili powder, garlic powder, fresh lemon juice, and butter, but you can add additional seasonings as well!
Adjustable Cooking Time. You can slow cook your fish on either the low or high setting, depending on when you want to eat. If you cook on high, be sure to check your fish's internal temperature at about 1 hour to prevent overcooking.
Tilapia Slow Cooker Ingredients
Here are the ingredients you will need to make this crockpot tilapia:
- Boneless Skinless Tilapia Fillets: try to look for fillets that are all about the same size, if possible, for even cooking to prevent overcooking.
- Chili Powder: add more or less for your desired heat level.
- Garlic Powder
- Coarse Sea Salt: you can also use kosher salt; adjust to taste.
- Ground Black Pepper
- Melted Butter: unsalted butter is preferred due to sea or kosher salt. If you use salted butter, you may need to adjust your salt (substitute olive oil instead of butter if desired).
- Lemon Juice: one regular-sized lemon yields about 2 tablespoons of fresh lemon juice. Adjust as needed--I always suggest extra fresh lemon for serving.
- Fresh Parsley: fresh chopped parsley is used for garnish.

Substitutions and Variations
- Substitute tilapia with haddock, sea bass, halibut, or cod.
- Use fresh cilantro in place of parsley if desired.
- Add other spices, such as crushed red pepper flakes, or add fresh sliced jalapeno to the crockpot to add fresh heat.
- Add fresh crushed or minced garlic for a more fragrant garlic flavor.
- You can use lime juice in place of lemon juice if preferred.
- Adding fresh sliced onion to your slow cooker adds a complementary flavor.
- Adjust the amount of fish needed for your family and adjust your seasonings for the amount as well.
- Use olive oil in place of butter if you would like to as well!

Slow Cooker Fish Tips
- Use similar-sized pieces of fish for consistent cooking. Place the thicker sides of tilapia over the thin sides of others to overlap and prevent overcooking your fish.
- Slow cookers do vary in temperature. Some can run very hot even when they are on low. Check your fish after 1-2 hours.
- Use a slow cooker liner or aluminum foil for easy cleanup.
- According to the USDA, the safe temperature for fish is 145 degrees F.
FAQ's
Transfer your fish to an air tight container once it has cooled. It should store in the fridge for up to 3 days.
Place your fish on a microwave-safe plate and cover. Microwave for 1 minute and continue to heat in 30-second increments until your desired temperature is met.
It is not necessary to soak your fish before cooking it. If you soak your fish, it could absorb too much water, disrupt the fish's integrity, and become mushy in texture versus tender and flaky.
Overcooking your fish will lead to a drier fillet, and the fish proteins constrict and become very tough and chewy.
Making sure that you add moisture to your slow cooker when cooking will assist in preventing your fish from drying out. Also, do not overcook your fish by checking your internal temperature so it doesn't exceed 145 degrees F.
