Ingredients
The Produce
-
2 bunches fresh collard greens
The Cheese Sauce (Roux Base)
-
2 tbsp butter
-
2 tbsp all-purpose flour
-
1½ cups whole milk
The Cheeses & Seasonings
-
1 cup shredded Gruyère or mozzarella cheese (divided)
-
¼ cup grated Parmesan cheese
-
½ tsp salt
-
¼ tsp black pepper
Step-by-Step Instructions
Step 1: Prep & Blanch the Collards
-
Preheat your oven to 375°F (190°C) and grease a medium baking dish.
-
Strip the leaves away from the tough center stems and chop into bite-sized pieces.
-
Bring a large pot of water to a boil, drop in the greens, and cook for 5 minutes.
-
Drain well in a colander.
Pro Tip: Press down with a spoon or wrap the cooked greens in a clean kitchen towel to squeeze out as much excess water as possible. This keeps your cheese sauce nice and rich instead of watery!
Step 2: Make the Sauce Base (Roux)
-
In a saucepan, melt the butter over medium heat.
-
Whisk in the flour and cook for about 1 minute until bubbling and fragrant (this cooks out the raw flour taste).
-
Slowly pour in the whole milk while whisking constantly to prevent lumps. Cook for a few minutes until thickened and smooth.
Step 3: Melt in the Cheese
-
Remove the saucepan from the heat.
-
Stir in half of the shredded Gruyère (or mozzarella), all of the grated Parmesan, salt, and black pepper until completely melted and velvety.
Step 4: Mix, Top, & Bake
-
Combine the blanched, well-drained collard greens with the hot cheese sauce until thoroughly coated.
-
Transfer the mixture to your prepared baking dish.
-
Sprinkle the remaining ½ cup of shredded Gruyère/mozzarella evenly over the top.
-
Bake for 20–25 minutes until the cheese is melted, bubbly, and lightly golden brown on top. Serve warm!
Blog Tips & Variations
-
Gruyère vs. Mozzarella: Gruyère adds a rich, nutty, complex flavor that pairs beautifully with earthy greens. If you prefer a milder taste with a classic “cheese pull,” mozzarella works wonderfully too!
-
Add a Crunchy Topping: For extra texture, mix ¼ cup of panko breadcrumbs with a tablespoon of melted butter and sprinkle over the cheese before baking.
