Variations

I love customizing this turkey and biscuits casserole depending on what’s in my fridge or what my family is in the mood for. Don’t hesitate to experiment—after all, food tastes best when it’s made your way.

Vegetarian Version: Swap turkey for sautéed mushrooms or chickpeas and extra peas for a satisfying meat-free twist – I’ve tried this on meatless Mondays and it’s a winner.
Seasonal Veggies: Add diced zucchini or roasted butternut squash in fall to keep the veggies interesting and seasonal.
Cheese Love: Mixing in some shredded cheddar or gouda with the parmesan can add smoky complexity if you want a deeper flavor profile.
Gluten-Free: Use a gluten-free flour blend in both the biscuit dough and sauce thickener for a gluten-free surprise that works like a charm.

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

Step 1: Sauté the Veggies for a Flavorful Base

First, melt 3 tablespoons of butter over medium heat in a large skillet. Add the chopped onion, carrot, and celery, cooking until soft and translucent—this usually takes about 6–8 minutes. Toss in the minced garlic during the last minute so it doesn’t burn but releases that gorgeous aroma. This is your flavor base, so don’t rush it!

Step 2: Make the Creamy Sauce

Stir in the flour and cook for a minute or two to get rid of the raw taste. Then slowly whisk in chicken broth and milk, stirring constantly until it thickens—about 5 minutes. This is where patience pays off because you want that perfectly smooth, gravy-like sauce. Mix in the dry mustard, Dijon mustard, salt, pepper, parmesan, fresh dill, lemon zest, and lemon juice. The sauce will smell incredible here!

Step 3: Combine the Filling

Gently fold in the cubed cooked turkey and frozen peas, making sure everything is coated well with the sauce. I love doing a quick taste test at this point to adjust seasoning—sometimes a pinch more salt or lemon juice is just what it needs. Transfer this filling to a 9×13-inch baking dish.

Step 4: Prepare Biscuit Topping

For the biscuits, combine the flour, sugar, baking powder, salt, and fresh dill in a bowl. Cut in the chilled butter until the mixture resembles coarse crumbs (I find a pastry cutter or two forks work wonders here). Stir in milk just until the dough comes together—it’s okay if it’s a bit sticky. Drop spoonfuls evenly over the turkey mixture in the casserole dish.

Step 5: Bake It Until Golden and Bubbling

Bake uncovered at 375°F (190°C) for about 30–35 minutes, or until the biscuit topping is golden brown and the filling is bubbly. If your biscuits brown too quickly, tent the casserole with foil halfway through baking. Once out of the oven, let it rest for 5–10 minutes before diving in—it helps the sauce set and makes serving easier.

Pro Tips for Making Turkey and Biscuits Casserole with Lemon and Dill Recipe

Use Day-Old Turkey: Leftover turkey tends to be drier, but it absorbs the creamy sauce beautifully, making the dish juicy and flavorful.
Don’t Overmix the Biscuit Dough: I learned that mixing too much makes tough biscuits, so I stop as soon as the dough holds together.
Fresh Dill Is a Game-Changer: Fresh herbs lift the dish in ways dried just can’t compete with—I always keep fresh dill on hand when making this casserole.
Let It Rest Before Serving: Waiting a bit lets the sauce thicken up so the casserole isn’t runny on the plate.

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

The image shows a white bowl filled with a creamy chicken and vegetable stew with visible chunks of orange carrots, green peas, and light beige chicken pieces, topped with two golden, slightly browned biscuit-like dumplings that have a rough, crumbly texture. The bowl is placed on a white marbled surface next to a silver spoon resting inside. Nearby, a rectangular white baking dish contains more of the stew and biscuit dumplings, showing a thick, creamy sauce with similar vegetables and chicken, topped by browned dumplings sprinkled with green herbs. Two whole yellow lemons, one cut in half, and a sprig of green dill are arranged beside the baking dish. Two clear glasses with lemon slices and a white cloth with red stripes are also on the white marbled surface. photo taken with an iphone --ar 2:3 --v 7 - Turkey and Biscuits Casserole with Lemon and Dill, easy turkey casserole, leftover turkey recipes, lemon dill chicken casserole, comforting holiday casserole

Garnishes

I like to sprinkle extra chopped fresh dill and a little lemon zest right on top before serving—it really brightens every bite and makes it look pretty on the table. Sometimes, a drizzle of good olive oil or a spoonful of crème fraîche adds a lovely creamy finish.

Side Dishes

This casserole is a meal on its own but goes wonderfully with a crisp green salad or steamed green beans tossed with butter and crushed almonds. Roasted Brussels sprouts with a sprinkle of parmesan also pair beautifully with the lemon and dill flavors.

Creative Ways to Present

For special occasions, I like to serve individual portions in small ramekins topped with biscuits piped on with a spoon or small scoop—makes it feel extra fanciful. And a garnish of microgreens or edible flowers never fails to impress guests without extra effort.

Make Ahead and Storage

Storing Leftovers

I keep leftovers covered tightly in the fridge and usually eat them within 3 days. The flavors actually deepen overnight, and the biscuit topping remains soft and tender—just like homemade comfort food should be.

Freezing

This casserole freezes well if you prepare it in advance without baking. I assemble it, cover tightly with foil, and freeze for up to 3 months. When ready, bake from frozen at 375°F (190°C), adding extra baking time until bubbly and golden on top.

Reheating

To reheat leftovers, I cover the dish with foil and warm it at 350°F (175°C) for about 20 minutes or until heated through. Removing the foil in the last 5 minutes helps refresh the biscuit topping’s crispness.

FAQs

Can I use fresh turkey instead of leftover turkey for this casserole?

Absolutely! If you have fresh turkey, simply cook and cube it before using. Just be sure it’s fully cooked and cooled. The casserole is flexible and works great with either fresh or leftover turkey.
Can I substitute the biscuits with a different topping?

Yes! Some people like to use puff pastry, mashed potatoes, or even cornbread as a topping. The biscuit topping adds texture and flavor, but feel free to swap it out based on your preferences or what’s on hand.
What can I do if I don’t have fresh dill?

If fresh dill isn’t available, dried dill can be used, but use it sparingly since it’s more potent. Adding lemon zest and juice will help brighten flavors to compensate.
How do I prevent the biscuits from getting soggy?

To keep biscuits from getting soggy, avoid over-spooning the dough too thickly and bake uncovered so moisture can escape. Also, letting the casserole rest before serving helps the filling set and keeps biscuits tender yet not mushy.

Final Thoughts

I can’t stress enough how much joy this Turkey and Biscuits Casserole with Lemon and Dill Recipe has brought my family’s table—turning leftover turkey into something fresh and exciting was a game-changer for me. If you want a dish that’s comforting yet bright, familiar but with a little twist, you’re going to want to give this one a try. Trust me, once you taste that combination of creamy lemon-dill filling and fluffy, buttery biscuits, it’ll become one of your go-to comfort recipes, especially when you’ve got turkey to use up.
