I discovered this recipe during a particularly hectic period when I was looking for ways to simplify my cooking without sacrificing flavor or nutrition. Growing up, my grandmother always made the most incredible roasted root vegetables, but they required at least an hour in the oven. When I got my Instant Pot, I wondered if I could recreate that same tender, caramelized texture in a fraction of the time. After several tests, I perfected this method that gives you all the flavor of traditional roasted vegetables with none of the hassle. The parsnips become wonderfully creamy and sweet, while the carrots retain just enough bite to keep things interesting. What makes this recipe special is the way the butter melts into the vegetables as they cook, creating this incredible glaze that coats every piece. The garlic adds a savory depth that balances the natural sweetness, and the fresh herbs brighten everything up. I love how the Instant Pot locks in all those flavors and moisture, so you don't end up with dry, sad vegetables. Every time I make this, I'm reminded that sometimes the simplest recipes are the most satisfying. It's become my secret weapon for impressing dinner guests without spending hours in the kitchen.
Why I love this recipe
What I love most about this recipe is how it transforms humble root vegetables into something truly special with minimal effort. There's something deeply satisfying about taking ingredients that are often overlooked and turning them into the star of the meal. The Instant Pot does all the heavy lifting, which means I can focus on other parts of dinner while these cook to perfection. I also appreciate how forgiving this recipe is – if you let it go a minute or two longer, the vegetables just become more tender, not ruined. The flavor combination is both comforting and sophisticated, making it appropriate for any occasion. I've served this at casual family dinners and formal holiday gatherings, and it's always met with compliments. The natural sweetness of the parsnips and carrots really shines through, enhanced rather than overwhelmed by the butter and herbs. It's also incredibly versatile – you can adjust the seasonings to match whatever else you're serving. Most importantly, this recipe reminds me that healthy eating doesn't have to be boring or complicated. These vegetables are packed with nutrients, fiber, and flavor, proving that wholesome food can also be absolutely delicious.
What You Need From Your Kitchen
- Parsnips: Peel and cut into 2-inch chunks for even cooking in the pressure cooker
- Carrots: Peel and cut into 2-inch chunks, matching the size of the parsnip pieces
- Butter: Use unsalted butter so you can control the saltiness, and melt it in the Instant Pot during sauté mode
- Garlic: Mince fresh cloves finely and sauté them in butter until fragrant before adding vegetables
- Vegetable Broth: Provides moisture and flavor for pressure cooking; can substitute with chicken broth
- Fresh Parsley: Chop finely and use as a bright, fresh garnish just before serving
Let's Make These Together
- Prep Your Vegetables
- Start by peeling all your parsnips and carrots with a vegetable peeler. Cut them into uniform 2-inch chunks so they cook evenly. The key is making sure all pieces are roughly the same size – this ensures some pieces won't be undercooked while others turn mushy. Place the cut vegetables in a bowl and set aside while you prepare the Instant Pot.
- Build the Flavor Base
- Turn your Instant Pot to Sauté mode and let it heat up for a minute. Add the butter and let it melt completely, then toss in the minced garlic. Stir constantly for about 60 seconds until the garlic becomes fragrant and just barely golden. Be careful not to burn the garlic as it can turn bitter. This aromatic base will infuse the entire dish with incredible flavor.
- Combine and Season
- Add your prepared parsnips and carrots to the pot, stirring them around to coat them in the buttery garlic mixture. Pour in the vegetable broth and sprinkle the dried thyme, salt, and pepper over everything. Give it all a good stir to distribute the seasonings evenly. The broth will create steam for pressure cooking while the seasonings will penetrate the vegetables as they cook.
- Pressure Cook to Perfection
- Secure the Instant Pot lid and make sure the valve is set to Sealing. Select High Pressure and set the timer for just 3 minutes. Yes, only 3 minutes! The Instant Pot is incredibly efficient at cooking vegetables quickly. The pot will take about 5-10 minutes to come to pressure before the cooking time begins, so factor that into your timing.
- Release and Serve
- When the cooking cycle completes, let the pressure release naturally for 5 minutes, then carefully switch the valve to Venting to release any remaining steam. Once the float valve drops, open the lid and marvel at your perfectly cooked vegetables. Give them a gentle stir – they'll be coated in a beautiful buttery glaze. Transfer to a serving dish, garnish generously with fresh chopped parsley, and serve immediately while they're piping hot.

Switch Things Up
I'll never forget the first time I made this recipe – it was a complete game-changer for my weeknight cooking routine. I had always roasted my root vegetables in the oven, which meant planning ahead and heating up the kitchen. One particularly busy Tuesday, I threw caution to the wind and decided to try the Instant Pot method instead. I was skeptical at first, thinking pressure-cooked vegetables might turn out mushy or bland. But when I opened that lid and saw those perfectly tender, buttery vegetables, I was sold. The parsnips had this incredible creamy texture, and the carrots were sweet and tender without being overcooked. My family devoured them so quickly that I had to make a second batch the very next day. Now this recipe is in my regular rotation, and I've even started experimenting with different herb combinations. Sometimes I add a splash of maple syrup for extra sweetness, or throw in some fresh rosemary for a more aromatic version. The beauty of this recipe is its versatility – it works as well for a casual family dinner as it does for a holiday gathering.
Perfect Pairings
These buttery parsnips and carrots pair beautifully with so many main dishes! Serve them alongside a perfectly roasted chicken with crispy skin, or next to a juicy herb-crusted pork tenderloin for a complete comfort meal. They're also fantastic with grilled salmon – the sweetness of the vegetables complements the rich, fatty fish perfectly. For a vegetarian feast, pair them with a creamy mushroom risotto or quinoa-stuffed bell peppers. Don't forget about holiday meals – these vegetables are a natural fit alongside turkey, ham, or prime rib. I also love serving them with simple pan-seared chicken breasts or lamb chops when I want something elegant but easy. The butter and herb flavors make these vegetables versatile enough to complement both simple weeknight proteins and special occasion centerpieces.

Frequently Asked Questions
- → Can I use frozen parsnips and carrots instead of fresh?
Yes, you can use frozen vegetables, but you don't need to thaw them first. Add them directly to the Instant Pot and increase the cooking time by 1-2 minutes to account for the frozen state. Keep in mind that frozen vegetables may release more liquid, so you might want to reduce the broth slightly.
- → How do I prevent my vegetables from turning mushy?
The key is not to overcook them. Stick to the 3-minute cooking time and don't skip the natural pressure release step. Also, make sure to cut your vegetables into uniform 2-inch chunks – smaller pieces will overcook quickly. If you prefer your vegetables with more bite, reduce the cooking time to 2 minutes.
- → Can I add other vegetables to this recipe?
Absolutely! Sweet potatoes, turnips, rutabaga, and even butternut squash work beautifully with this cooking method. Just make sure to cut everything into similar-sized pieces. Root vegetables with similar cooking times work best together – avoid adding quick-cooking vegetables like zucchini or bell peppers as they'll turn to mush.
- → What can I use instead of butter to make this dairy-free?
You can substitute olive oil, avocado oil, or coconut oil for the butter. For a richer flavor similar to butter, try using ghee or vegan butter. The vegetables will still be delicious, though the flavor profile will be slightly different. You might want to add a squeeze of lemon juice at the end for extra brightness.
- → How should I store and reheat leftovers?
Store leftover vegetables in an airtight container in the refrigerator for up to 4 days. To reheat, you can microwave them in 30-second intervals, stirring between each interval, or warm them gently in a skillet over medium heat with a little extra butter or oil. Avoid reheating in the Instant Pot as they'll become overcooked.
- → Can I make this recipe without an Instant Pot?
Yes! You can roast the vegetables in a 400°F oven for 30-40 minutes, tossing halfway through, or steam them on the stovetop for 15-20 minutes until tender. The Instant Pot method is faster and requires less monitoring, but traditional methods work great too. Just toss the cooked vegetables with the butter, garlic, and herbs at the end.
Conclusion
This Instant Pot Parsnips and Carrots recipe is proof that simple ingredients can create extraordinary results. The pressure cooking method locks in all the natural sweetness of these root vegetables while the butter and herbs add richness and depth. Whether you're serving this alongside roasted chicken, grilled steak, or as part of a vegetarian feast, these vegetables shine every single time. The best part? You can have this elegant side dish ready in under 20 minutes, making it perfect for busy weeknights or last-minute dinner parties. Once you try this method, you'll never go back to traditional roasting!
