Autumn Chicken Dinner with Roasted Vegetables – One Skillet, Yummy Easy Food

Sweater weather brings out a very specific craving in our house, and nothing satisfies it quite like a big skillet of Autumn Chicken Dinner with Roasted Vegetables landing on the table on a chilly evening. There’s something about the smell of roasting butternut squash mixing with garlic butter on the stove that makes the whole kitchen feel like fall arrived right on schedule.

This dish came together as an answer to a fairly common weeknight problem: wanting something that tastes like a proper harvest-season meal without actually spending the whole evening in the kitchen. Tender chicken thighs, caramelized butternut squash, roasted Brussels sprouts, and pillowy cheese tortellini all come together in one skillet, tossed in a garlic butter sauce that ties every component together. It’s the kind of Autumn Chicken Dinner with Roasted Vegetables that manages to feel indulgent and genuinely nourishing at the same time.

What really sets this dish apart is how much flavor comes from just letting the oven and the skillet do their jobs properly. The vegetables roast until their edges turn deeply golden and caramelized, concentrating their natural sweetness in a way that steaming or boiling never could. Meanwhile, the chicken gets a proper sear in a hot cast-iron skillet, developing a golden crust before it even meets the garlic butter sauce. By the time everything gets tossed together with the tortellini, you’ve got a dish where every single bite carries a different texture and flavor.

This Autumn Chicken Dinner with Roasted Vegetables also solves the eternal weeknight dilemma of wanting something substantial without leaving behind a sink full of dishes. Beyond the two baking sheets for roasting, everything else happens in one skillet, which makes cleanup dramatically simpler than juggling multiple pots and pans for a meal with this many components. That’s a small thing on paper, but it makes a real difference on a Tuesday night when nobody has the energy for an extended cleanup session.

There’s also a real sense of balance built into this recipe. Protein from the chicken, fiber from the Brussels sprouts, natural sweetness from the butternut squash, and comforting carbs from the cheese tortellini all show up in the same dish, which means this genuinely works as a complete, satisfying dinner rather than something that needs three side dishes to feel whole. If you’ve been hunting for easy simple dinner recipes healthy enough to feel good about but still comforting enough to actually crave, this fits that description well.

What’s been especially nice about making this Autumn Chicken Dinner with Roasted Vegetables on repeat throughout the season is how well it adapts to whatever else is going on. Cooking for a busy weeknight? It comes together with minimal hands-on effort once the vegetables are in the oven. Hosting a cozy weekend gathering instead? The same recipe scales up easily and looks like it took a lot more effort than it actually did. Either way, it delivers exactly the kind of hearty, seasonal flavor that makes autumn cooking so satisfying in the first place.

Whether you’re looking for new recipes for fall dinner to add to your rotation, or you’re just craving something warm and comforting now that the weather’s turned, this dish checks every box. It’s the kind of recipe that quietly becomes a household staple the moment the leaves start changing color.

Here’s a look at what goes into this dish without exact amounts attached — the full measurements are on the printable recipe card below. I’ll walk through what each ingredient contributes, so you understand how the recipe comes together and where you have room to adjust it.

• Butternut squash — roasted until caramelized, this brings natural sweetness and a hearty, satisfying texture to the dish.
• Brussels sprouts — roasted alongside the squash, these add fiber, a slightly nutty flavor, and a nice textural contrast once golden and crisp at the edges.
• Olive oil — used for both roasting the vegetables and searing the chicken, helping everything develop a proper golden color.
• Chicken thighs — stay juicy and flavorful through the searing process, forming the protein backbone of this Autumn Chicken Dinner with Roasted Vegetables.
• Smoked paprika — seasons the chicken with a subtle smoky depth that complements the roasted vegetables beautifully.
• Cheese tortellini — brings a comforting, pillowy texture that soaks up the garlic butter sauce and rounds out the meal.
• Butter — the base of the garlic sauce, adding richness that coats the tortellini and chicken.
• Garlic — sautéed in the butter, this builds the fragrant, savory backbone of the whole finishing sauce.
• Fresh thyme, salt, and black pepper — simple seasonings that tie every component of the dish together at the end.

How to Make It

For the exact ingredient amounts, check the printable recipe card below.

1. Roast the vegetables. Toss the butternut squash and Brussels sprouts separately with olive oil, salt, and pepper, then roast until golden and tender.
2. Cook the tortellini. Boil the cheese tortellini according to package instructions, then drain and set aside.
3. Sear the chicken. Season sliced chicken thighs with smoked paprika, salt, and pepper, then sear in a hot skillet until golden and cooked through.
4. Make the garlic butter sauce. Melt butter in the same skillet and sauté the garlic until fragrant.
5. Combine everything. Toss the tortellini in the garlic butter, add back the chicken, then fold in the roasted vegetables. Season, garnish with thyme, and serve.

Pro Tips for Perfect Autumn Chicken Dinner with Roasted Vegetables

Use a heavy-duty cast-iron skillet. Even heat distribution helps the chicken develop a deep, golden sear rather than cooking unevenly.

Roast the vegetables at a high temperature. This is what creates those crispy, caramelized edges that give the vegetables so much flavor in this Autumn Chicken Dinner with Roasted Vegetables.

Don’t crowd the baking sheets. Giving the squash and Brussels sprouts enough space ensures they roast and crisp up properly instead of steaming.

Pat the chicken dry before searing. Removing excess moisture helps the chicken develop a better crust once it hits the hot skillet.

Don’t overcook the tortellini. It will continue to soften slightly once tossed with the hot garlic butter sauce, so pulling it right at al dente keeps the texture from turning mushy.

Variations to Try

Swap the protein. Chicken breast works in place of thighs, though thighs tend to stay juicier through the searing process.

Change up the pasta. Spinach or meat-filled tortellini both work well in place of cheese tortellini if you want to switch up the flavor.

Try a different vegetable base. Sweet potatoes make a great substitute for butternut squash, offering a slightly different but equally satisfying flavor profile.

Add more vegetables. Carrots or parsnips make excellent additions if you want to round out the harvest flavors even further.

Add a little heat. A pinch of red pepper flakes stirred into the garlic butter brings a subtle warmth that plays nicely against the sweetness of the roasted squash.

Best Ways to Serve Autumn Chicken Dinner with Roasted Vegetables

With a crisp green salad. A simple side salad with balsamic dressing adds freshness alongside this rich, comforting dish.

Alongside crusty garlic bread. Perfect for soaking up any leftover garlic butter sauce in the skillet.

Topped with parmesan. A sprinkle of freshly grated parmesan adds an extra savory finish right before serving.

With a light beverage pairing. A glass of sparkling apple cider complements the warm, seasonal flavors nicely without overpowering the meal.

As part of a family gathering spread. This dish works beautifully as a simple family dinner centerpiece, especially when everyone’s craving something cozy and filling.

Storage and Leftovers

How should I store Autumn Chicken Dinner with Roasted Vegetables? Keep leftovers in an airtight container in the refrigerator for up to 3 days.

How do I reheat it? Warm it in a skillet over medium-low heat with a small splash of water or broth to loosen the sauce back up. Avoid microwaving for too long, since the pasta can turn mushy.

Can I roast the vegetables ahead of time? Yes, they can be roasted up to 24 hours in advance and stored in the fridge until you’re ready to combine everything.

Is this recipe freezer-friendly? The roasted vegetables can lose some of their texture after freezing, so this dish is best enjoyed fresh rather than frozen.

Instructions

Step 1: Roast the Seasonal Vegetables

Preheat your oven to 400°F. In a large mixing bowl, toss the cubed butternut squash with a portion of the olive oil along with a generous pinch of salt and pepper, making sure every piece is evenly coated. Spread the seasoned squash out in a single, even layer across a parchment-lined baking sheet, giving the pieces enough space so they roast rather than steam. Place the sheet in the oven and roast for 30 minutes, until the squash turns tender and caramelized at the edges.

In a separate bowl, toss the halved Brussels sprouts with the remaining olive oil and another pinch of salt and pepper. Spread them out on their own separate parchment-lined baking sheet, again avoiding overcrowding, and roast for 20 to 30 minutes, until they turn deeply golden brown and crisp around the edges.

Step 2: Prepare the Tortellini

Bring a large pot of generously salted water to a rolling boil over high heat. Add the cheese tortellini and cook according to the package instructions, checking a minute or so before the suggested time, until the pasta is tender but still holds its shape, known as al dente. Once cooked, drain the tortellini thoroughly in a colander and set it aside until you’re ready to combine everything in the final step.

Step 3: Sear the Chicken

Slice the boneless, skinless chicken thighs into thin strips. Season the strips evenly on all sides with the smoked paprika, salt, and black pepper. Set a large cast-iron skillet over medium heat and let it preheat for about 3 minutes, until it’s properly hot. Add a drizzle of olive oil to the skillet, then arrange the seasoned chicken strips in a single, even layer, making sure not to overcrowd the pan. Let the chicken cook undisturbed for about 4 minutes on the first side, resisting the urge to move it around, so it develops a deep, golden crust. Flip the strips over and continue cooking until the chicken is fully cooked through with no pink remaining. Once done, transfer the chicken to a plate and set it aside.

Step 4: Create the Garlic Butter Sauce

Using the same skillet you just cooked the chicken in — without cleaning it, so you keep all those flavorful browned bits — reduce the heat to low-medium and add the butter, letting it melt completely. Add the minced garlic to the melted butter and sauté, stirring frequently, for 1 to 2 minutes, until it turns fragrant and softened. Keep a close eye on the garlic during this step, since it can go from perfectly golden to burnt and bitter very quickly at this heat.

Step 5: Combine and Serve

 

Add the drained, cooked tortellini directly into the skillet with the garlic butter, tossing gently so every piece gets coated in the sauce. Return the cooked chicken strips to the pan, stirring them in among the tortellini. Gently fold in the roasted butternut squash and Brussels sprouts, being careful not to break up the vegetables too much as you mix everything together. Once combined, sprinkle the fresh thyme over the top and give the whole dish a final taste, adjusting the salt and pepper as needed. Serve immediately while everything is still hot.

Notes

• Chicken breast can be substituted for chicken thighs if preferred, though thighs tend to stay noticeably juicier throughout the searing process.
• For variety, cheese tortellini can be swapped for spinach-filled or other vegetable-filled tortellini varieties without changing the rest of the method.
• Sweet potatoes can replace butternut squash for a different, equally delicious flavor profile if that’s what you have on hand.
