Can I use chicken breast instead of chicken thighs?

While you could, it’s not recommended for this recipe. Thighs stay juicy and flavorful through the baking process, whereas breasts often dry out. If you must use breasts, watch the cooking time very carefully.

What if I can’t find crème fraîche?

Full-fat sour cream works well as a substitute, offering the tang and creamy consistency needed. Just be sure it’s also at room temperature to avoid curdling.

Can I prep elements of this bake in advance?

Absolutely! You can cook the chicken, vegetables, and sauce earlier in the day, then assemble and finish with potatoes right before baking. This makes dinnertime even faster.

What’s the best way to get a crispy potato topping?

Par-cook the potatoes as directed and don’t overcrowd them on top of the bake. For an even more golden crust, broil for the last 2–3 minutes—but keep a close eye so nothing burns.

Ingredients You’ll Need

This bake shines because every ingredient serves a real purpose and can be swapped or adapted to suit you. Here’s what goes in and why:

Boneless Skinless Chicken Thighs: Essential for juicy, flavor-packed bites that stay moist. Avoid chicken breast, which dries out too easily.
Asparagus: Adds color and crunch. Thin works best, but you can use thicker if you don’t mind a softer texture.
Pancetta: Infuses a gorgeous smokiness and savory depth to the sauce.
Shallots: Bring mild sweetness and subtle flavor without overpowering.
Garlic: Because every good bake needs a garlicky undertone.
Unsalted Butter: The secret to a rich, silky sauce.
Plain Flour: Thickens the sauce to glossy perfection.
Chicken Stock: Deepens the poultry flavor and pulls everything together.
Full-Fat Crème Fraîche: Lends incredible creaminess and tang. Room temperature, always, to avoid curdling.
Fresh Tarragon: The hero—fresh is best for that bright punch.
Baking Potatoes: Form the golden, crispy, can’t-skip-it topping.
Parmesan: Satisfyingly salty and adds crispness on top; trust me, don’t hold back.
Olive Oil: Helps everything get that perfect color during roasting.
Salt & Pepper: Essential for seasoning every layer to bring the flavors to life.

How to Make Tarragon Chicken Bake

Getting this glorious meal on your table is easier than you’d think. Here’s exactly how to do it:

Step 1: Brown the Chicken

Drizzle olive oil into a large pan over medium-high heat. Season diced chicken thighs with salt and pepper, then fry both sides until golden and almost cooked through. This builds flavor, so don’t rush! Remove the chicken and set aside.

Step 2: Cook the Asparagus

In the same pan, toss in the chopped asparagus. Fry until it just starts to take color and soften—remember, it’ll finish cooking in the oven. Transfer to a separate bowl.

Step 3: Build the Flavor Base

Lower heat to medium and add pancetta. Sauté until it gets slightly crispy and releases its fat. Add shallots, cooking until they turn soft and golden, then stir in your garlic. After a minute, melt in the butter.

Step 4: Create the Sauce

Mix in the flour to make a roux, then slowly whisk in chicken stock, keeping things smooth. Stir in crème fraîche and fresh tarragon for that creamy, fragrant sauce. Add the cooked chicken (plus any juices) back in. Let everything simmer for 7–8 minutes until the sauce thickens.

Step 5: Assemble the Bake

Preheat your oven to 200°C/400°F. Stir the asparagus back into the pan, then pour everything into a baking dish. Let it cool while you prep the potatoes.

Step 6: Roast the Potatoes

Toss diced potatoes with olive oil, salt, and pepper on a baking tray. Roast for about 18–20 minutes—just until they’re fork-tender but not super crispy.

Step 7: Bake Until Golden

Gently scatter roasted potatoes over the chicken mixture in the baking dish, closing up any gaps, and top with parmesan. Bake for another 18–20 minutes, watching that the potatoes don’t brown too quickly (gently press them down if needed).

Step 8: Garnish and Serve

Sprinkle a pinch of extra tarragon over the hot bake before serving. Dig in and enjoy—preferably while everything is piping hot and bubbling!

Pro Tips for Making the Recipe

Room Temperature Crème Fraîche: This can’t be said enough. Cold crème fraîche might curdle—leave it out while you prep ingredients.
Golden Chicken = Big Flavor: Don’t skip browning your chicken first. It adds so much depth.
Mind the Potatoes: If some potato cubes are browning faster than others, gently press them into the sauce halfway through baking.
Fresh Tarragon Matters: Dried tarragon isn’t nearly as vibrant. If you really must substitute, use half the amount, but fresh is worth finding.
Batch Cooking: You can double this for a crowd—just use a larger baking dish.

How to Serve

This Tarragon Chicken Bake is a whole meal in itself—creamy, cheesy, herby, filling. But if you’re in the mood for sides, a crisp green salad or some tender stem broccoli tucked alongside offers wonderful balance. For a little extra, warm crusty bread is a dream for mopping up any leftover sauce on your plate. Don’t forget a sprinkle of extra fresh tarragon before serving—it’s the finishing touch that brightens everything up.

Make Ahead and Storage

Storing Leftovers

Cool any leftovers before transferring them to an airtight container. Store in the fridge for up to 3 days. The flavors deepen as it sits!

Freezing

This bake freezes beautifully. Portion it into airtight containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

To reheat, warm the bake in a covered dish in the oven (180°C/350°F) for 20–25 minutes or until piping hot, or simply microwave individual servings until heated through.

Note: If reheating from frozen, always defrost thoroughly first. Add a splash of extra chicken stock or cream when reheating if the sauce thickens too much.
