Chicken Divan Sauce Recipe: Velvety Sherry and Cheese Infusion

This velvety sauce transforms chicken divan from good to extraordinary. A perfect blend of sherry and cheese creates a rich, smooth texture that clings beautifully to every bite.

With just a few simple ingredients and 15 minutes of your time, you can make this sauce that elevates the dish to restaurant-quality status. The sherry adds depth while the cheese provides that comforting creaminess everyone loves.

Ingredients for Chicken Divan Sauce

Ten ingredients. Fifteen minutes. A sauce that feels like a restaurant splurge.

The sherry is non-negotiable here—it’s doing the heavy lifting for that restaurant-quality depth. Look for dry sherry in the cooking wine section at Whole Foods or Total Wine. Don’t waste good sipping sherry on this (save that for your glass). The cheddar should be sharp and block-form—pre-shredded has anti-caking agents that make the sauce grainy. I always grab Cabot or Tillamook for consistent quality.

No sherry? Dry white wine works in a pinch (just avoid sweet varieties). For a non-alcoholic swap, extra chicken broth with a splash of apple cider vinegar gets you 80% there. The mustard can be yellow if that’s what you’ve got, but Dijon adds that nice sharpness. Out of cheddar? Gruyère or Monterey Jack melt beautifully—just avoid pre-shredded. Freshly grated is worth the extra two minutes.

This sauce thickens as it cools. Store in an airtight container in the fridge for up to 4 days. Reheat gently with a splash of milk to restore that velvety texture. Doesn’t freeze well—the dairy can separate. Best made fresh for that perfect cling to every bite.

Step-by-Step Instructions for Chicken Divan Sauce

This velvety sauce comes together with a few key techniques and careful timing.

Step 1: Create a Smooth Roux Base

Melt the 0.5 cup unsalted butter in a heavy saucepan over medium heat. As it foam subsides, whisk in the 0.25 cup all-purpose flour all at once. The mixture will look shaggy at first—keep whisking constantly for 2-3 minutes until it smooths into a golden paste.

You’re building the foundation here. The roux should bubble gently but not brown—this is a white roux for maximum thickening power. If it starts to darken, reduce the heat immediately. The flour needs to cook out its raw taste without taking on color.

Step 2: Gradually Incorporate the Liquids

Slowly whisk in the 1.5 cups whole milk and 1 cup chicken broth, adding about ¼ cup at a time. Wait until each addition is fully smooth before adding more. This gradual process prevents lumps from forming in your sauce.

Once all the liquid is incorporated, add the 0.25 cup dry sherry, 2 tsp Worcestershire sauce, 1 tbsp Dijon mustard, 0.5 tsp salt, and 0.25 tsp ground black pepper. Bring the mixture to a gentle simmer, stirring frequently, for 5-7 minutes until it thickens enough to coat the back of a spoon.

Step 3: Achieve the Perfect Cheese Melt

Reduce the heat to low and begin adding the cheeses. Sprinkle in the 1.5 cups sharp cheddar cheese and 0.5 cup Parmesan cheese a handful at a time, whisking constantly between additions. This slow incorporation ensures a smooth, lump-free sauce.

After each addition, wait until the cheese is nearly completely melted before adding more. The sauce should become silky and cohesive, with no graininess. If it seems too thick, whisk in a splash of warm milk to reach your desired consistency. Taste and adjust seasoning if needed.

Step 4: Finish and Serve Immediately

Once all the cheese is melted and the sauce is velvety smooth, remove it from the heat. The sauce will continue to thicken slightly as it cools, so serve it within 5-10 minutes for the best texture.

Pour this rich, creamy sauce over your prepared chicken and broccoli, then return to the oven to bake until bubbly. The sherry adds a subtle depth that complements the sharp cheddar perfectly, while the Parmesan gives it that final touch of umami richness.

Make-Ahead Tips for chicken divan sauce

Prep Ahead Strategy

You can prepare the roux base up to 2 days in advance. Cook the butter and flour mixture, then let it cool completely before storing in an airtight container at room temperature. This gives you a head start on sauce day. 💡

Cheese Prep

Grating the sharp cheddar and Parmesan ahead of time saves minutes during cooking. Store the grated cheese in a sealed container in the fridge for up to 3 days. Just bring it to room temperature before melting for the smoothest texture.

Liquid Measurements

Pre-measure all your liquids the night before. Combine the whole milk, chicken broth, and dry sherry in a large measuring cup. Cover and refrigerate. This streamlines the cooking process significantly.

Storage Tips

The completed sauce keeps beautifully in the fridge for up to 4 days. Use an airtight container and press plastic wrap directly against the surface to prevent a skin from forming. Reheat gently with a splash of milk. ❄️

Freezing Not Recommended

While you can freeze this sauce, the dairy can separate upon thawing, resulting in a grainy texture. If you must freeze, do so for no longer than 1 month and reheat very slowly with constant whisking.

Day-Of Assembly

If using in chicken divan, assemble the entire casserole up to 1 day ahead. Keep it covered in the fridge, then bake as directed, adding 10-15 minutes to the cooking time since it’ll start cold.
