Creamy Cheesy Grits

Cajun Catfish
- Cooking Oil. Olive oil or avocado oil will work great here.

How to Make Fish and Grits
I suggest making the grits first, so the fish is nice and hot when you're ready to serve.
Creamy Cheesy Grits
Add chicken broth to a deep saucepan over medium-high heat. Cover the pot until the liquid boils. Then whisk in grits. Add butter and garlic and then cover for 5-10 minutes, stirring constantly.
Then add cheese and heavy cream, whisking until creamy. Season with salt and pepper to taste. Set the creamy grits aside and keep warm. Occasionally stir it so it doesn't begin to clump.
Cajun Catfish
Add cooking oil to a sauté pan or cast iron pan on medium-high heat. Season the fish liberally with cajun seasoning. When the pan begins to smoke, add the cajun fish and sear on both sides for 3-5 minutes, or until cooked through.
Squeeze lemon wedges over the fish and let the juices cook out. Remove the fish from the pan and set aside.
Reduction Sauce
Then add chicken broth to the pan. Use a whisk to release charred bits on the bottom of the pan. Pour in heavy cream and stir until the sauce is reduced and begins to thicken. Turn off the heat and set aside until plating.
Tips and Tricks
- If your grits are runny, allow them to rest. Grits tend to thicken as they sit. You can also try to drain excess liquid. If the grits are too thick, add broth or heavy cream.
- Remember to consistently stir the grits as they cook. This prevents clumping.
- Wash your saucepan as soon as possible because the grits will adhere to the pot, making it harder to scrub the pan clean, the longer it sits.
Recipe Variations
- Cooking Method: I opted out of frying fish (which is true Southern tradition) for this recipe since we are in small living quarters but you can definitely make fried fish and grits instead.
- Fish: You can make cajun fish with a variety of fish. I also like salmon and rockfish with this recipe.
- Grits: If you don't mind a longer cooking time, you can use stone-ground grits instead of quick grits. It's heartier, less processed, and more in line with traditional Southern grits. You can also use yellow grits instead of white grits. Yellow grits are great if you prefer sweeter grits.
- Cheese: You can use sharp cheddar cheese or parmesan cheese instead for a different flavor.
How to Store Leftovers
Store leftover fish and grits separately, in airtight containers in the fridge. The fish and sauce will last up to 2 days, whereas the grits will last up to 4 days.
You can reheat the leftovers in the microwave. Alternatively, warm up the grits over medium-low heat on the stovetop. You may need to add a splash of broth or heavy cream to loosen it up.
