How to Make Charred Corn Avocado Salad with Roasted Red Onions
Preheat the oven: Set your oven to 200°C (400°F) so it’s hot and ready for the red onions.
Slice and season onions: Halve the two red onions lengthwise and place them cut side down in a baking tray. Drizzle with olive oil and a sprinkle of sea salt. Roast on the lower rack for 30 minutes until they’re soft and golden brown.
Cool and slice onions: Once roasted, remove the onions from the oven and let them cool slightly. Peel off the skins and slice them into approximately 1cm thick layers. Set aside, separating the layers for a better presentation.
Prepare the grill: While the onions are roasting, heat up your grill pan to medium-high. This is where the magic of the charred corn will happen!
Grill the corn: Coat the three corn cobs with olive oil, and season them generously with salt and pepper. Grill for about 15 minutes, turning occasionally until they’re nicely charred. Once done, let them cool.
Cut the kernels: Carefully cut the grilled corn kernels off the cobs and place them into a mixing bowl. Their sweet smokiness is going to add amazing flavor!
Prep the tomatoes: Rinse the 200 g of red grape tomatoes and 200 g of yellow grape tomatoes, then cut them in half lengthwise to release their juicy goodness.
Cube the avocado: Slice the avocado into cubes, about 2cm in size. Its creamy texture will balance out the other crunchy ingredients perfectly.
Tear the cilantro: Rinse your ¼ bunch of cilantro and tear the leaves into smaller pieces, releasing their fresh aroma. Feel free to adjust the amount based on your preference!
Make the dressing: In a mason jar, combine 2 tbsp of olive oil, 2 tsp of lemon juice, 1 tbsp of Dijon mustard, and 1 tbsp of maple syrup. Add salt and pepper to taste. Secure the lid and shake until well mixed.
Combine everything: In a large serving bowl, mix together the grilled corn, roasted red onions, avocado, and both kinds of tomatoes. Drizzle the dressing over and toss gently. Sprinkle with torn cilantro leaves, give it another light mix, and season with more salt and pepper if desired. Serve and enjoy!
Optional: Top with crumbled feta for an extra touch of flavor!

Expert Tips for Charred Corn Avocado Salad
Choose Fresh Produce: Opt for the freshest corn and ripe avocados. This elevates the flavor of your Charred Corn Avocado Salad with Roasted Red Onions immensely.
Don’t Rush Roasting: Allow your red onions to roast until golden and tender. Rushing this step can result in a raw, harsh taste instead of sweet caramelization.
Perfectly Grilled Corn: Make sure to rotate the corn regularly while grilling to achieve even charring. This enhances the smoky flavor that’s vital to your salad.
Cool Ingredients: Let the grilled corn cool slightly before mixing it in. This preserves the avocado’s texture and prevents it from becoming mushy.
Balance the Dressing: Taste your dressing before adding it to the salad. Adjust the lemon juice, salt, and maple syrup to create a balance that suits your palate.
Serve Fresh: For the best experience, serve your salad immediately after mixing to enjoy the freshness of the ingredients in your Charred Corn Avocado Salad with Roasted Red Onions.
How to Store and Freeze Charred Corn Avocado Salad with Roasted Red Onions
Fridge: Store leftovers in an airtight container for up to 2 days. The salad may become soggy, so it’s best to keep the dressing separate until ready to serve.
Freezer: Freezing is not recommended for this salad due to the avocado and fresh veggies, which can alter in texture once thawed.
Reheating: If you prefer your corn warm, you can briefly microwave it before serving, but keep the rest of the salad cold for the best experience.
Freshness Tip: Serve your Charred Corn Avocado Salad with Roasted Red Onions fresh for optimal taste and texture.

Switch the Dressing: Try a balsamic vinaigrette or yogurt-based dressing for a different flavor profile. These options add zestiness that complements the roasted veggies.
Grill Other Veggies: Toss in some grilled bell peppers or zucchini for a smoky sweetness. Their vibrant colors will make your salad even more visually appealing!
Nutty Addition: Add a handful of toasted pine nuts or chopped walnuts for crunch and a nutty flavor. They offer an unexpected twist that elevates the dish.
Herb Variations: Substitute basil or mint for cilantro to create a fresh twist. Each herb brings its unique character, making every bite feel new.

Charred Corn Avocado Salad with Roasted Red Onions Recipe FAQs
What should I look for when selecting ripe avocados?
Absolutely! When selecting avocados, look for ones that yield slightly to gentle pressure, indicating ripeness. Avoid any with dark spots all over, as they may be overly ripe or spoiled. If they’re too firm, let them ripen at room temperature for a few days.
How should I store leftovers of this salad?
To store leftovers, place the salad in an airtight container and refrigerate for up to 2 days. However, I recommend keeping the dressing separate until you’re ready to enjoy your salad again. This helps prevent the ingredients from becoming soggy.
Can I freeze my Charred Corn Avocado Salad with Roasted Red Onions?
Freezing this salad is not recommended, as the avocado and fresh ingredients can lose their texture once thawed. If you’re looking to prepare in advance, consider grilling the corn and making the dressing ahead of time, then combine everything fresh!
What should I do if my corn isn’t fully charred?
If your corn doesn’t achieve that lovely char after grilling, don’t worry! Simply return it to the grill for an additional 2-3 minutes, turning it more frequently for even coloring. Remember, the more char, the better the flavor!
Are there any dietary considerations I should keep in mind?
Yes, if you’re serving this salad to guests or family, it’s good to ask about allergies. Avocados are typically safe, but some people may have issues with certain ingredients in the dressing, like Dijon mustard. You can easily substitute it with a gluten-free mustard if needed.
What’s the best way to prepare this salad ahead of time?
For those who love to meal prep, here’s what I recommend: cook the corn and roast the onions a day in advance. Store them separately in airtight containers in the fridge. Combine all the ingredients on the day you plan to serve to enjoy the freshest taste. Just mix the dressing shortly before serving for the best results!
