Prepare to fall in love with a truly indispensable recipe that will quickly become a cherished staple in your culinary repertoire. These rustic herb roasted onions, inspired by the legendary Ina Garten, are not just incredibly delicious but also remarkably versatile and visually appealing. They embody the essence of effortless elegance, transforming humble onions into a dish that’s both comforting and sophisticated. Once you try them, you’ll understand why this recipe is a definite keeper – they are simply irresistible!
This delightful recipe for Herb Roasted Onions was thoughtfully selected by Kelly from Baking with the Boys as her contribution to one of November’s Barefoot Bloggers challenges. The Barefoot Bloggers community is a fantastic initiative where food enthusiasts come together to explore and cook through Ina Garten’s iconic recipes, sharing their experiences and adaptations. When I first saw the chosen recipes for that month, a wave of excitement washed over me. While every past Barefoot Bloggers recipe has been a journey of discovery and deliciousness, these particular selections felt like a perfect fit, requiring minimal fuss and adjustments on my part.
For those who know my cooking style, you’ll be aware of my perpetual quest to “lighten up” dishes wherever possible – it’s almost an ingrained habit, a culinary addiction, if you will. And if you’re familiar with Ina Garten’s philosophy, you know her recipes are famously generous, often featuring luxurious ingredients like rich butter, decadent cream, and ample olive oil. It’s part of what makes her “Barefoot Contessa” creations so incredibly comforting and universally loved. However, what makes these Herb Roasted Onions so brilliant is their inherent simplicity and incredible flavor profile, which doesn’t rely on excessive richness. This recipe truly lets the natural goodness of the onions shine through, making it a delicious exception to the rule and a testament to Ina’s genius.
The Irresistible Charm of Roasted Onions
Let’s talk more about these magnificent onions. Roasting is a magical cooking method that transforms humble vegetables, and onions are no exception. The high heat of the oven coaxes out their natural sugars, leading to a beautiful caramelization and an incredible depth of sweetness that raw onions simply don’t possess. This process mellows their pungent edge, creating tender, succulent bites that are bursting with flavor. The combination of red and yellow onions in this recipe not only adds visual appeal but also a subtle complexity in taste, with red onions offering a slightly milder, sweeter profile and yellow onions a robust, earthy note.
Versatility: A Side Dish for Every Occasion
One of the most appealing aspects of these Herb Roasted Onions is their phenomenal versatility. They are a truly exceptional side dish that complements almost any main course imaginable. Picture them alongside a perfectly seared steak, where their sweetness cuts through the richness of the meat, or as a rustic accompaniment to a succulent roast chicken, enhancing the flavors with their aromatic herbs. But don’t stop there! These onions are equally fantastic with grilled fish, roasted pork loin, or even as a flavorful component in a vegetarian meal. Their comforting yet elegant nature makes them suitable for a simple weeknight dinner or a more elaborate gathering.
Beyond being a stellar side, these roasted onions are fantastic for repurposing. Got leftovers? They elevate a simple sandwich into something extraordinary. Imagine them nestled in a warm ciabatta with some goat cheese and fresh greens. They’re also incredible when scrambled with eggs for a gourmet breakfast or brunch, adding a sweet and savory kick. Consider tossing them into a warm grain bowl, topping a homemade pizza, or stirring them into a pasta dish for an instant flavor boost. They might even gracefully sneak their way onto your Thanksgiving table, offering a fresh, vibrant contrast to traditional heavy fare. In my opinion, they are absolutely worthy of a place at any celebratory feast.
The Secret to Unforgettable Flavor: The Zesty Dressing
What truly sets this recipe apart, even after the onions have reached their tender, caramelized perfection, is the brilliant addition of the reserved dressing. Drizzling this fresh, zesty vinaigrette over the warm roasted onions just before serving creates a harmonious balance of flavors. The bright acidity from the freshly squeezed lemon juice cuts through the sweetness of the roasted onions, while the piquant Dijon mustard adds a subtle tang. Minced garlic provides an aromatic foundation, and fresh thyme leaves infuse the dish with an earthy, herbaceous essence. A generous amount of good quality olive oil binds these ingredients together, creating a vibrant sauce that awakens the palate.
This final touch imparts such a wonderfully fresh taste, elevating the onions beyond mere sweetness. It’s a testament to the power of simple, high-quality ingredients working in concert. This isn’t just cooking; it’s an ode to “real food” – honest, straightforward, and incredibly satisfying. It’s simplicity at its absolute best, proving that you don’t need complicated techniques or exotic ingredients to create something truly memorable and deeply flavorful. The light sprinkle of fresh parsley at the end adds another layer of freshness and a pop of color, making the dish as appealing to the eye as it is to the taste buds.

Ina Garten’s Herb Roasted Onions Recipe

Ingredients for Herb Roasted Onions:
- 2 red onions
- 1 yellow onion
- 2 tablespoons freshly squeezed lemon juice
- 1 teaspoon Dijon mustard
- 1 teaspoon minced garlic
- 1/2 tablespoon minced fresh thyme leaves
- 3/4 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
- 1/4 cup good olive oil
- 1/2 tablespoon minced fresh parsley leaves
Directions for Preparing Herb Roasted Onions:
- Preheat your oven to 400 degrees F (200 degrees C). This ensures the onions roast evenly and develop that beautiful caramelization.
- Prepare the onions: Carefully remove the stem end of each onion. Slice off the dry, brown part of the root end, making sure to leave the root intact. Keeping the root intact helps hold the onion wedges together during roasting. Peel away the outer layers of the onion. Stand each onion upright on a cutting board with the root end facing up, and then cut the onion into wedges, slicing through the root. Place these wedges into a large mixing bowl.
- Prepare the dressing: In a separate, large bowl, combine the freshly squeezed lemon juice, Dijon mustard, minced garlic, fresh thyme leaves, kosher salt, and freshly ground black pepper. Whisk these ingredients together until well combined. Slowly drizzle in the good quality olive oil while continuously whisking to create an emulsified vinaigrette. This slow addition helps the dressing come together smoothly.
- Combine and roast: Pour the prepared dressing over the onion wedges in the bowl. Toss thoroughly to ensure all the onion pieces are evenly coated with the flavorful vinaigrette. Using a slotted spoon, transfer the seasoned onions to a large sheet pan, making sure to reserve any excess vinaigrette that remains in the bowl – this will be used later.
- Bake the onions for 30 to 45 minutes, or until they are beautifully tender and caramelized with browned edges. For even cooking and consistent browning, toss the onions once halfway through the baking process.
- Finish and serve: Once roasted, remove the onions from the oven. Drizzle them generously with the reserved dressing, which will add a fresh, vibrant kick. Sprinkle with the minced fresh parsley leaves for an added burst of color and flavor. Season to taste with additional salt and pepper if desired. Serve these exquisite Herb Roasted Onions warm or at room temperature – they are delicious either way!

Reflecting on Culinary Journeys and Community
Speaking of blogging adventures and delicious creations, I’m reminded of another exciting moment from last August when I embarked on my first “joust” (a friendly blogging challenge). That culinary escapade resulted in these incredibly yummy Ginger Gelato Sandwiches. It was an absolute thrill, and I was especially grateful when Sophie from Key Ingredient graciously featured the recipe on her blog, The Back Burner. Her write-up was wonderfully detailed and truly captured the essence of the dessert, and I cannot thank her enough for the exposure and kind words. If you’re curious about that sweet adventure, I highly encourage you to go check out her feature here!
These experiences, whether discovering a beloved Ina Garten recipe or being celebrated for a unique dessert, highlight the vibrant and supportive community that thrives around food blogging. It’s about sharing passion, inspiring others, and continually exploring new culinary horizons. And just like these Herb Roasted Onions, which are a testament to simple ingredients yielding extraordinary results, the joy of cooking often lies in the connections we make and the stories we share around the table, or in this case, through our blogs.
