Ingredients
Instructions
1. Preheat your oven to 400 F (200 C). Peel and quarter your mixed onions. If they are very large, you can cut them into sixths or eighths to ensure even cooking. Arrange them in a single layer on a large baking sheet.
2. In a small bowl, whisk together 2 tablespoons of olive oil, maple syrup, Dijon mustard, apple cider vinegar, dried thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until well combined.
3. Pour the maple Dijon mixture over the quartered onions on the baking sheet. Toss gently with your hands or a spatula to ensure all the onions are evenly coated. Spread them back into a single layer.
4. Place the baking sheet in the preheated oven and roast for 25-30 minutes, or until the onions are tender and slightly caramelized at the edges. Give them a stir halfway through cooking to promote even browning.
5. While the onions are roasting, heat the remaining 2 tablespoons of olive oil in a small skillet over medium heat. Add the thinly sliced shallot rings and cook, stirring frequently, for 5-8 minutes, or until they are golden brown and crispy. Watch them carefully as they can burn quickly. Remove them from the pan with a slotted spoon and place them on a paper towel-lined plate to drain any excess oil. Season lightly with a pinch of salt.
6. Once the onions are tender and slightly browned, remove them from the oven. Transfer them to a serving dish and generously sprinkle the crispy shallots over the top. Serve warm.

What You’ll Love About This Quick And Easy Recipe
This Maple Dijon Onion Boil is a fantastic addition to any family’s recipe rotation because it’s incredibly versatile and universally appealing.

Parents will appreciate how simple it is to prepare, requiring basic ingredients and straightforward steps, making it ideal for busy weeknights. Kids often enjoy the slightly sweet and savory flavor profile, especially with the fun texture of crispy shallots.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients for this dish is a breeze, as most items are likely already in your pantry or easily found at any grocery store. The key to its deep flavor lies in the quality of the onions and the balance of the maple-Dijon dressing. Don’t worry if you don’t have every exact item; there are plenty of simple substitutions you can make without compromising the delicious outcome.
INGREDIENTS:

- 2 pounds mixed onions (yellow, red, or sweet), peeled and quartered
- 1/4 cup olive oil, divided
- 2 tablespoons maple syrup
- 1 tablespoon Dijon mustard
- 1 tablespoon apple cider vinegar
- 1/2 teaspoon dried thyme
- 1/4 teaspoon black pepper
- 1/2 teaspoon salt, plus more to taste
- 2 large shallots, thinly sliced into rings
For the onions, a mix of yellow and red onions adds a beautiful color and a slightly more complex flavor, but using just one type works perfectly fine. If you don’t have maple syrup, honey can be a good substitute, though it will alter the flavor slightly. Dijon mustard is crucial for that tangy kick, but a whole-grain Dijon can add an interesting texture. For the shallots, if you can’t find them, a very small amount of finely minced red onion can be fried until crispy, but shallots truly offer the best texture and milder flavor for crisping.

How To Make It Step By Step With Visual Cues

Making this Maple Dijon Onion Boil is a straightforward process. Follow these steps for perfectly tender onions and irresistibly crispy shallots.
- Prepare the onions: Preheat your oven to 400°F (200°C). Peel and quarter your mixed onions. If they are very large, you can cut them into sixths or eighths to ensure even cooking. Arrange them in a single layer on a large baking sheet.
- Whisk the dressing: In a small bowl, whisk together 2 tablespoons of olive oil, maple syrup, Dijon mustard, apple cider vinegar, dried thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until well combined.
- Dress the onions: Pour the maple Dijon mixture over the quartered onions on the baking sheet. Toss gently with your hands or a spatula to ensure all the onions are evenly coated. Spread them back into a single layer.
- Roast the onions: Place the baking sheet in the preheated oven and roast for 25-30 minutes, or until the onions are tender and slightly caramelized at the edges. Give them a stir halfway through cooking to promote even browning.
- Prepare crispy shallots: While the onions are roasting, heat the remaining 2 tablespoons of olive oil in a small skillet over medium heat. Add the thinly sliced shallot rings and cook, stirring frequently, for 5-8 minutes, or until they are golden brown and crispy. Watch them carefully as they can burn quickly. Remove them from the pan with a slotted spoon and place them on a paper towel-lined plate to drain any excess oil. Season lightly with a pinch of salt.
- Serve and enjoy: Once the onions are tender and slightly browned, remove them from the oven. Transfer them to a serving dish and generously sprinkle the crispy shallots over the top. Serve warm.
Easy Variations And Serving Ideas That Fit Real Life
This Maple Dijon Onion Boil is incredibly adaptable, making it easy to fit into any meal plan or dietary preference.
- Add a protein boost: For a more complete meal, toss in some chickpeas or white beans with the onions before roasting. Cooked sausage or chicken pieces can also be added during the last 10-15 minutes of roasting.
- Spice it up: A pinch of red pepper flakes added to the dressing can give it a subtle heat, perfect for those who enjoy a little kick.
- Herb swap: Instead of dried thyme, try dried rosemary or a blend of Italian herbs. Fresh herbs like chopped parsley or chives can be sprinkled on top just before serving for a burst of freshness.
- Kid-friendly approach: If your children are sensitive to strong onion flavors, use only sweet onions (like Vidalia) and consider reducing the Dijon mustard slightly in the dressing. The crispy shallots are usually a big hit with kids!
- Serving suggestions: This dish pairs beautifully with roasted meats like pork loin or chicken. It’s also fantastic alongside a simple pan-seared fish. For a vegetarian meal, serve it over a bed of fluffy couscous, quinoa, or with a hearty piece of crusty bread to soak up the delicious juices. It can also be a wonderful addition to a brunch spread.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have pitfalls. Knowing these common mistakes will help you achieve perfect results every time.
- Overcrowding the baking sheet: If you pile too many onions onto one sheet, they will steam instead of roast, resulting in soft, watery onions instead of tender, caramelized ones. Use two baking sheets if necessary to ensure a single layer.
- Burning the shallots: Crispy shallots can go from perfectly golden to burnt in a matter of seconds. Keep a close eye on them, stir frequently, and remove them from the heat as soon as they reach a deep golden color. They will continue to crisp up as they cool.
- Unevenly cut onions: If some onion pieces are much larger than others, they will cook at different rates. Try to cut your onion quarters to a similar size for consistent tenderness.
- Forgetting to stir the onions: Stirring the onions halfway through roasting helps them to brown evenly on all sides and prevents them from sticking to the baking sheet.
- Not seasoning enough: Onions release a lot of moisture, which can dilute flavors. Don’t be shy with the initial salt and pepper, and always taste before serving to adjust if needed.
How To Store It And Make It Ahead Without Ruining Texture
This Maple Dijon Onion Boil is best enjoyed fresh, but you can certainly prepare parts of it in advance or store leftovers.
- Storing leftovers: Any leftover roasted onions can be stored in an airtight container in the refrigerator for up to 3-4 days. The crispy shallots are best stored separately in a small airtight container at room temperature to maintain their crispness. If stored with the onions, they will become soft.
- Reheating: Reheat the roasted onions gently in the microwave or in a skillet over medium heat until warmed through. If you want to restore some caramelization, you can reheat them in a preheated oven at 350°F (175°C) for about 10-15 minutes. Add the reserved crispy shallots just before serving.
- Make-ahead tips: You can peel and quarter the onions a day in advance and store them in an airtight container in the refrigerator. The maple Dijon dressing can also be whisked together ahead of time and stored in the fridge. This makes assembly on the day of cooking incredibly fast. While you can pre-fry the shallots, they are truly at their best when made fresh right before serving. However, if time is extremely tight, you can fry them a few hours in advance and store them uncovered at room temperature to keep them crisp.
