Method
Step 1
- Wash the russet potatoes with the skin on, then cut them into wedges and slice into even fry strips.

Step 2
- Place the potatoes in a large bowl of cold water and soak for at least 1 hour to remove excess starch.

Step 3
- Drain the potatoes and dry them completely using paper towels.

Step 4
- Heat vegetable oil in a cast iron skillet to 350°F.

Step 5
- Fry the potatoes in batches for 8–10 minutes, or until golden brown and crispy.

Step 6
- Remove fries from oil and place on a paper towel-lined baking sheet. Season immediately with garlic salt, paprika, and cajun seasoning.

Step 7
- In a saucepan over medium heat, melt the butter.

Step 8
- Whisk in the flour and cook until a smooth paste forms.

Step 9
- Slowly add the warm milk while whisking continuously until the sauce thickens slightly.

Step 10
- Stir in the white cheddar cheese until fully melted and smooth.

Step 11
- Gently fold in the lump crab meat and Old Bay seasoning.

Step 12
- Spread the fries evenly in a baking dish and pour the crab cheese sauce over the top.

Step 13
- Sprinkle the yellow cheddar cheese evenly on top.

Step 14
- Bake in a 375°F oven for 15–20 minutes, until the cheese is melted and bubbly.

Step 15
- Remove from the oven, garnish with green onions if desired, and serve immediately.

Notes
I always recommend drying the fries really well before frying because moisture causes oil splatter and soggy fries. Freshly shredded cheese melts better than pre-shredded, and lump crab meat gives the best balance of flavor and texture for this recipe.
