Roasted Garlic & Pearl Onions with Herbs: A Sweet, Savory, and Utterly Irresistible Side Dish

There are certain aromas that, when wafting from the oven, immediately transport me back to my grandmother’s bustling kitchen. The scent of slow-roasting garlic, its pungent bite mellowing into a sweet, buttery richness, is one of them. It conjures memories of Sunday dinners, where bowls of this glistening, herb-infused goodness would appear alongside everything from succulent roasts to simple crusty bread. It was never just a side dish; it was an invitation to savor, to share, and to experience the magic that simple ingredients, treated with time and heat, can create. This recipe, which I’ve tinkered with over the years, from a single bulb to a veritable mountain, is my ode to those cherished moments.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 1 hour
• Total Time: 1 hour 15 minutes
• Servings: 30
• Yield: 1 Big Jar full
• Dietary Type: Vegan, Gluten-Free, Dairy-Free

Ingredients

• 1/4 cup olive oil
• 20 bulbs garlic (or as little or as much as you want!)
• 1 lb white pearl onion (optional)
• Salt and pepper to taste
• 2 four-inch sprigs rosemary, minced
• 4 four-inch sprigs thyme, minced

Equipment Needed

• Oven
• Heavy-bottomed pan or aluminum foil
• Basting spoon or brush

Instructions

1. Begin by preparing your garlic bulbs and pearl onions. For the garlic, carefully slice off the very top, pointed end of each bulb, exposing the cloves within. For the pearl onions, if you’re using them, trim off their root end and peel away the papery outer layers.
2. In a bowl, toss the prepared garlic bulbs and pearl onions with the 1/4 cup of olive oil. Ensure they are evenly coated.
3. Season generously with salt and pepper to your liking. Then, sprinkle in the minced rosemary and thyme, distributing the fragrant herbs throughout the mixture.
4. Now, it’s time to roast. You have two excellent options for achieving that perfect caramelization:
   • Foil Method: Arrange the seasoned garlic and onions on a large piece of aluminum foil. Create a loose pouch by bringing the edges together, but crucially, keep the top open. This is key to allowing the moisture to escape and achieve a beautiful caramelization rather than steaming.
   • Pan Method: Alternatively, place the seasoned garlic and onions directly into a heavy-bottomed pan.
5. Regardless of your chosen method, the next step is to bake them in a preheated oven at 375°F (190°C) for 1 hour.
6. About halfway through the cooking time, if you opted for the pan method, gently baste the garlic and onions with the olive oil that has collected at the bottom of the pan. This ensures they remain moist and continue to develop their rich flavor.
7. Once the 1 hour of baking is complete, your roasted garlic and pearl onions will be tender, sweet, and deeply golden. They are now ready to be used in a myriad of ways!

Expert Tips & Tricks

The beauty of roasted garlic and pearl onions lies in their versatility. Once roasted, you can truly use them with whatever your heart desires. For those who prefer an even more concentrated flavor, or if you’re looking to store this treasure for future culinary adventures, consider these options:

• Creating a Roasted Garlic Spread: After roasting, carefully remove the softened garlic cloves from their skins and scoop out the tender pearl onions. You can then combine these with any reserved olive oil from the pan. For an intensely flavorful spread, gently heat the olive oil in the same roasting pan, scraping up all the flavorful bits from the bottom. Allow this infused oil to cool slightly, then pour it over the extracted garlic and onions in a clean container. Refrigerate, and you’ll have a ready-to-use condiment that elevates everything.
• Freezing for Later: If you’ve made a large batch, you can extract the garlic and onions from their skins and store them in an airtight container in the freezer. This makes it incredibly easy to add a burst of roasted flavor to dishes on demand.
• Stocking Up on Flavor: Don’t discard the skins of the garlic and onions after extracting the roasted goodness! Save them to add to your vegetable stock for an extra layer of depth and sweetness.

Serving & Storage Suggestions

These Roasted Garlic & Pearl Onions with Herbs are a culinary chameleon, fitting in perfectly with countless dishes. My personal favorite is spreading the luscious, softened garlic onto fresh, crisp bread – pure, unadulterated bliss. They are also a divine addition to mashed potatoes, lending an incredible depth of flavor and a creamy texture. Toss day-old bread cubes with some of the roasted mixture and a drizzle of its infused oil to create exceptional croutons for salads or soups.

For storage, if you haven’t opted for the freezing method, the roasted vegetables and their infused oil can be kept in an airtight container in the refrigerator for up to a week. Reheat gently in a pan with a little extra olive oil, or simply enjoy them at room temperature.

Variations & Substitutions

While this recipe is delightful as is, feel free to explore its potential:

• Herbal Variations: Swap the rosemary and thyme for other complementary herbs like sage, marjoram, or even a touch of finely chopped parsley for a brighter note.
• Spicy Kick: Add a pinch of red pepper flakes along with the salt and pepper for a hint of heat.
• Balsamic Glaze: After roasting, a drizzle of balsamic glaze over the top adds a wonderful sweet and tangy dimension.
• Root Vegetable Medley: While not part of this specific recipe, you could certainly roast chunks of carrots, parsnips, or sweet potatoes alongside the garlic and onions for a more substantial side dish.

FAQs

Q: Why is it important to keep the foil pouch open when roasting garlic and onions?
A: Keeping the top open allows steam to escape, preventing the vegetables from becoming waterlogged and instead encouraging them to caramelize and develop a sweeter, richer flavor.

Q: Can I use regular onions instead of pearl onions?
A: Yes, you can use regular yellow or white onions, cut into wedges or chunks, though they may not caramelize quite as evenly as pearl onions.

Q: How do I know when the garlic and onions are done roasting?
A: The garlic cloves should be very soft and spreadable when squeezed from their skins, and the onions should be tender and have golden-brown edges.

Q: Is it better to use fresh herbs or dried herbs?
A: Fresh herbs are recommended for this recipe as they impart a more vibrant and nuanced flavor. If you must use dried herbs, use about one-third the amount of fresh herbs.

Q: Can I roast more garlic bulbs at once?
A: Absolutely! You can easily scale up the recipe. Just ensure your pan or foil pouch is large enough to accommodate all the garlic and onions without overcrowding, allowing them to roast properly.
