Catfish and grits is one of those southern dishes that doesn't care what time of day it is — breakfast, brunch, lunch, or dinner, this plate works. I've been cooking variations of this in my kitchen and on the menu at my DC restaurant Fraîche for years, and this is the version I've landed on after a lot of testing. It builds on three things most home recipes skip: a proper Cajun trinity gravy, andouille sausage for smoky depth, and a parmesan-gouda grit base that drinks up everything around it. Crispy fried catfish goes on top, and the whole thing comes together in under an hour.

Why This Recipe Works

What is catfish and grits? Catfish and grits is a southern dish featuring crispy fried catfish served over creamy stone-ground grits, often paired with a savory gravy. This Cajun-influenced version uses a parmesan and gouda grit base, andouille sausage gravy with the holy trinity of onion, bell pepper, and celery, and a flour-dredged catfish for maximum crunch. It works as breakfast, brunch, lunch, or dinner.

• The 4-to-1 grit ratio with milk and stock. Most home cooks use water. Two cups chicken stock plus two cups whole milk for every one cup of grits delivers richness and savor that water alone can't.
• Andouille gravy, not cream sauce. The Cajun trinity sweated in andouille fat, finished with a roux and stock, builds a flavored gravy that drinks down into the grits. It's the difference between "good" and "restaurant."
• Cook the components in the right order. Grits first (they reheat fine), gravy second, fish last. Frying catfish at the end means it hits the plate hot, crispy, and uncompromised.

Ingredients You'll Need

This catfish and grits recipe has three components — creamy cheese grits, andouille Cajun gravy, and crispy fried catfish. Here's everything you'll need:

For the Grits

• 1 cup stone-ground grits
• 2 cups chicken stock
• 2 cups whole milk
• 1 cup shredded gouda
• ½ cup shredded parmesan
• 2 tablespoon butter
• 1 teaspoon chicken bouillon powder
• 1 tablespoon AP Seasoning
• Salt to taste

For the Andouille Gravy

• 8 oz andouille sausage, sliced into half-moons
• 2 tablespoon butter
• 1 yellow onion, diced (or ½ large onion)
• ½ bell pepper, diced
• 2 stalks celery, diced
• 1 tablespoon minced garlic
• 2 tablespoon tomato paste
• ¼ cup Seasoned Flour (or all-purpose flour seasoned with salt, pepper, garlic powder, onion powder, cayenne)
• 2 cups chicken stock
• 1 teaspoon Cajun seasoning
• 1 teaspoon chicken bouillon powder
• 1 tablespoon AP Seasoning
• Fresh parsley, chopped

For the Fried Catfish

• 3 catfish fillets (6–8 oz each)
• 1 tablespoon Texas Pete or your favorite hot sauce
• 1 tablespoon AP Seasoning
• 1 large egg
• 1 tablespoon yellow mustard
• 1½ cups Seasoned Flour
• Vegetable oil for frying

Catfish and Grits Substitutions and Variations

• No andouille? Chicken or beef andouille works for non-pork eaters. Smoked sausage or kielbasa is a backup, though you'll lose some of the spice.
• Catfish → tilapia, snapper, or trout. Any flaky white fish works. Catfish is traditional for the southern flavor profile and holds up best to frying.
• Cornmeal coating. Add ¼ cup cornmeal to the seasoned flour for an extra-crunchy southern fish-fry style crust.
• Cheese swap. Sharp cheddar in place of gouda still works. Avoid pre-shredded — the anti-caking agents prevent smooth melt.
• Spice it up. Add diced jalapeño with the trinity for more heat. Bump cayenne in the gravy.
• Lighter version. Use 2% milk and skip the parmesan to lighten the grits. Bake the catfish at 425°F for 12 minutes instead of frying.

How to Make Catfish and Grits Step by Step

1. Cook the grits first. In a saucepan, combine 2 cups chicken stock and 2 cups milk. Season with chicken bouillon and AP Seasoning. Bring to a gentle boil, then whisk in 1 cup of grits in a steady stream to prevent clumping. Reduce heat to low.

2. Stir and finish the grits. Cook over low heat for 5 to 7 minutes, stirring frequently to prevent sticking. Once thickened, stir in 2 tablespoons of butter, 1 cup gouda, and ½ cup parmesan. Taste and adjust salt. Cover and set aside — the grits will hold and reheat fine.

3. Render the andouille. In a skillet over medium heat, melt 2 tablespoons of butter. Add the sliced andouille and cook 4 to 5 minutes until the sausage caramelizes and releases its fat. This fat is the flavor base for the entire gravy.

4. Sweat the trinity. Add diced onion, bell pepper, and celery directly to the andouille and butter. Cook 4 to 5 minutes until softened. Add minced garlic and cook 30 seconds.

5. Build the roux. Stir in the tomato paste and cook 1 to 2 minutes until it darkens. Sprinkle in the seasoned flour and stir constantly for 2 to 3 minutes until the raw flour smell is gone — this is your roux.

6. Add stock and season. Pour in 2 cups chicken stock while whisking. Add Cajun seasoning, chicken bouillon, and AP Seasoning. Bring to a simmer and cook 8 to 10 minutes until thickened to a gravy consistency. Stir in fresh parsley off heat. Cover and hold.

7. Prep the catfish. Pat the catfish fillets dry. Hit each fillet with a few dashes of hot sauce and a sprinkle of AP Seasoning on both sides. In a shallow bowl, whisk together the egg and yellow mustard.

8. Dredge. Dip each fillet in the egg-mustard mixture, letting excess drip off. Press into the seasoned flour, coating completely with no bald spots. Set on a rack while the oil heats.

9. Fry. Heat oil to 350°F in a heavy skillet or Dutch oven. Fry the catfish 3 to 4 minutes per side until deep golden brown and crispy. Internal temp should hit 145°F. Drain on a wire rack — never paper towels (they trap steam and make the crust soggy).

10. Plate. Spoon a generous portion of grits into the bottom of a shallow bowl. Lay the catfish on top. Ladle andouille gravy over the fish, letting it pool into the grits. Garnish with parsley and serve immediately.

Pro Tips for the Best Catfish and Grits

• Whisk grits in slowly while the liquid is boiling. Pouring all at once causes lumps that won't smooth out no matter how long you cook them. A steady stream while whisking is the only move.
• Render the andouille hard. Most cooks rush this step. The browned sausage and rendered fat are 60% of your gravy's flavor — don't move on until you see real caramelization.
• Don't shred cheese from a bag. Pre-shredded cheese is coated with anti-caking agents that prevent smooth melt. Buy a block, grate it yourself. Two extra minutes for a noticeably better grit base.
• Mustard in the egg wash is a southern trick. It doesn't add flavor — it helps the flour bind to the fish for a thicker, crunchier crust. Skip it and your breading falls off mid-fry.
• Drain on a rack, not paper towels. Paper towels trap steam under the fish and turn your crispy crust soggy in 60 seconds. A wire rack lets air circulate and keeps the fry texture intact.

Catfish and Grits Storage and Reheating

• Fridge: Store grits, gravy, and catfish separately in airtight containers up to 3 days.
• Freezer: Gravy freezes well up to 2 months. Grits get grainy when frozen — make fresh. Catfish should not be frozen after cooking.
• Reheat grits: Stovetop with a splash of milk or stock to loosen. Whisk constantly.
• Reheat gravy: Stovetop, low heat, splash of stock if it's thickened too much.
• Reheat catfish: 400°F oven on a wire rack for 6 to 8 minutes. Never microwave fried fish — the crust goes from crispy to rubbery in seconds.
