The first time I cooked with endive I was a little skeptical. I was warned of the bitterness but wanted to give it a shot nonetheless. Cooking it unveils its mildly sweet flavor, so I decided to do just that for this recipe. Roasting the endive removes a lot of that distinct bitterness, transforming it into a slightly sweet, slightly nutty delicacy. And we’re amping it up another level by adding the makings for a gratin – bechamel sauce and gruyere cheese! The result is a decadent dish that’s high on flavor, packed with veggies, and perfect as a dinner main course or side.
Ingredients in Belgian Endive Gratin
Endive gratin is divided into three ingredient components: the endives, the sauce, and the cheese. Together, this meal becomes a savory, cheesy, filling dish that you’re going to crave again and again!
Endives
Belgian Endives: First, you will need 8 individual Belgian endives, which you can find in the produce aisle of many grocery stores. This will create 4 hefty servings! Olive Oil: 2 tablespoons of olive oil will be used to help the endives brown up when baking.
Bechamel
Butter: First up for the bechamel sauce is 2 tablespoons of unsalted butter. If using salted butter, simply omit the salt from this recipe. Flour: Next, 3 tablespoons of all purpose flour thickens up the sauce and helps it achieve the correct consistency. Milk: 2 cups of warm milk will add the liquid component to the sauce. I recommend regular dairy milk, either low-fat or whole. Nut milk will add an undesired flavor. Salt & Cayenne Pepper: Finally, complete the sauce with a pinch of salt and a pinch of cayenne pepper.
Assembly
Gruyere: No gratin is complete without cheese! You’ll need 1 cup of grated gruyere, divided. Parmesan: Finish off the dish with ¼ cup of grated parmesan cheese.
What is bechamel?
Bechamel is one of my favorite parts of this recipe. It brings the whole dish together and creates a creamy, cheesy meal! If you’re unfamiliar, bechamel is a white sauce made with milk, flour, and butter. It’s found in many French and Greek recipes and can actually be used as a substitute for ricotta (like in this lasagna)!
How to make baked endive gratin
Belgian endive au gratin begins by roasting the endive in the oven. We’ll coat it with olive oil to make it nice and golden brown. Then, we’ll create the bechamel and assemble everything in a dish. Top with cheese and broil, and that’s it! Step 1: Roast the endivePreheat the oven to 425ªF (218ªC). Cut most of the tough root off of each endive, leaving just enough to keep the endive intact. Cut each in half lengthwise and arrange cut side down on a baking sheet. Drizzle with olive oil, rubbing evenly to coat. Roast for 30 minutes, or until fork tender. Step 2: Create the bechamelMelt the butter in a medium saucepan over medium heat. Add the flour, whisking to combine, and cook for about a minute. While whisking, slowly pour in the milk. Once fully incorporated, increase the heat to reach a gentle simmer until the sauce thickens. Stir in the salt, cayenne, and half of the gruyere. Step 3: Assemble the gratinIn a large casserole dish, spread a third of the bechamel sauce onto the bottom, and then tightly pack in the cooked endives. Top evenly with the remaining bechamel and sprinkle with the remaining cheeses. Step 4: Broil the dishSet the oven to broil and place the pan on the middle rack. Broil, watching closely, until the cheese is melty and golden.
Endive Gratin Tips
Dish Size: I used a 9×13 casserole dish, and it worked well with 8 endives. You can use whatever size you have, but I recommend keeping the endives to one layer for optimal cooking. If using an 8×8 dish, you’ll probably need 5 or 6 endives. Swapping Gruyere: Not everyone loves gruyere, and that’s okay! Mozzarella makes another tasty option. Choosing Endives: When shopping for endives, look for those that are yellow vs. green. The endives with yellow coloring are usually fresher and have a better taste!
