• Herb Swap: I’ve tried parsley instead of dill, and while dill is my go-to, parsley makes a nice mild alternative.
• Dairy-Free: Use a plant-based milk and vegan butter to make this casserole dairy-free without losing creaminess.
• Vegetable Boost: Add mushrooms or spinach to the filling if you want extra greens or earthiness.
• Spicy Fix: For a little kick, sprinkle in some red pepper flakes or chopped jalapeño.

How to Make Turkey and Biscuits Casserole with Lemon and Dill Recipe

Step 1: Sauté the Veggies for a Flavorful Base

Start by melting 3 tablespoons of butter in a large skillet over medium heat. Add the chopped yellow onion, carrot, and celery, and cook them slowly until they soften—about 8 minutes. This slow sauté releases their natural sweetness, which is the secret behind that irresistible, comforting base in the casserole. Stir in the minced garlic and cook for another minute until fragrant. Be careful not to brown the garlic too much, or it can get bitter.

Step 2: Make the Creamy Turkey Filling

Sprinkle in the all-purpose flour and stir to coat the veggies. This creates a roux that will thicken the sauce perfectly. Slowly whisk in the chicken broth and whole milk. Be patient here so you get a smooth, lump-free sauce. Then, add dry mustard, Dijon mustard, kosher salt, black pepper, and Parmesan cheese, stirring until everything melds together. Now, fold in fresh dill, lemon zest, and juice—which is where this Turkey and Biscuits Casserole with Lemon and Dill Recipe really shines with its bright flavor. Finally, toss in the cubed turkey and frozen peas, letting the heat gently thaw the peas and warm the turkey through.

Step 3: Prepare the Dill-Infused Biscuit Topping

While the filling cools a bit, mix the biscuit ingredients in a bowl: flour, sugar, baking powder, salt, fresh dill, milk, and chilled, diced butter. Use your fingers or a pastry cutter to work the butter in until the mixture resembles coarse crumbs. Then add the milk and gently stir until just combined—you want soft dough, but don’t overmix or the biscuits will turn tough! This biscuit dough adds the perfect fluffy, buttery layer on top.

Step 4: Assemble and Bake Your Casserole

Spoon the turkey filling into a greased casserole dish, spreading it out evenly. Then dollop spoonfuls of biscuit dough over the top, leaving a little space between each. This helps the biscuits bake evenly and puff up beautifully. Bake at 375°F (190°C) for about 35-40 minutes until the biscuits are golden brown and the casserole is bubbling. You’ll want to watch the edges so the biscuits don’t overbrown, but a little crust adds great texture.

How to Serve Turkey and Biscuits Casserole with Lemon and Dill Recipe

Garnishes

I usually finish the dish with a sprinkle of freshly chopped dill and a little extra lemon zest right before serving. It adds a lovely fresh aroma and a splash of color that makes the casserole feel even more inviting. Sometimes a light drizzle of good-quality olive oil adds that little extra shine and richness.

Side Dishes

This casserole is pretty complete on its own, but I love pairing it with a crisp green salad or steamed green beans to add vibrancy and crunch. Roasted root vegetables or a simple cucumber-dill salad also complement the lemony dill flavors wonderfully, balancing out the richness of the casserole.

Creative Ways to Present

For special occasions, I sometimes bake this casserole in individual ramekins, which makes serving feel extra cozy and personal. Another fun trick is sprinkling a little more grated Parmesan on the biscuit topping before baking to get a cheesy, golden crust that wow guests every time.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge, and they usually keep well for up to 3 days. The flavors actually deepen overnight, so it often tastes even better the next day. Just cover it tightly to keep the biscuits from drying out.

Freezing

You can freeze this casserole, either fully assembled or just the turkey filling. I recommend freezing before adding the biscuit topping because biscuits freeze better that way. Thaw overnight in the fridge before baking fresh biscuits on top and finishing in the oven for that just-baked goodness.

Reheating

To reheat leftovers, cover with foil and warm in a 350°F oven until heated through, about 20 minutes. If you want to refresh the biscuits, I pop the casserole in uncovered the last 5 minutes so they crisp back up. Microwaving works in a pinch but tends to soften the biscuits.
