Roasted Tomato and Garlic Aioli Sauce is lip-smackin’ good. The recipe combines roasted Roma tomatoes, red onion, whole cloves of garlic, and thyme. All of these ingredients contribute to the depth of flavor found in this dipping sauce. An array of spices, chipotle pepper in adobo sauce, Tabasco sauce, and of course mayo round this dip to perfection. Warning: addictive in every way.
Roasted Tomato and Garlic Aioli Sauce is ridiculously simple to make. There are two steps, seriously two steps to this smoky, spicy garlicky dip. #1 – Roasting the Vegetables. #2 – Puréeing everything in a food processor. Well, of course, then devouring this divine concoction with my Crispy Baked Sweet Potato Fries or Smoky Grilled Sweet Potato Rounds.
How to Make This Aioli
- Roma Tomatoes – These are the star of the show. It sets the stage for every other ingredient. Roma tomatoes are best for sauces because they have more flesh and less liquid than a salad tomato. They are also known as plum tomatoes.
- Red Onion – you could use a sweet onion as well. I probably wouldn’t grab a yellow onion because they tend to be a little more bitter than I would like for this recipe.
- Garlic – the name “aioli” translates to garlic oil. So definitely garlic is a factor in this Roasted Tomato and Garlic Aioli Sauce.
- Olive Oil
- Fresh Thyme
- Kosher Salt and Freshly Ground Pepper
- Smoked Paprika – This adds a nice smoky flavor to the sauce.
- Ground Cumin – A warm, earthy taste that adds a bit of peppery flavor. It complements the roasted tomatoes.
- Chipotle Chili Powder – This has moderate heat to it. There’s a rich depth of flavor along with extra smokiness.
- Mayonnaise – Mayo is the base of the aioli and gives it a creaminess.
- Chipotle Pepper in Adobo Sauce – Brings some added heat.
- Hot Pepper Sauce (Tabasco) – Because Tabasco is just GOOD.
- Splash White Wine Vinegar – You can use lemon juice as well.
Step #1 – Roast the Vegetables and Thyme
Cut Roma tomatoes in half lengthwise and lay in a roasting pan cut side up. Cut a red onion into 2-inch chunks. Add the onion along with the tomatoes and large garlic cloves (skin-on). Sprinkle generously with salt and pepper. Lay whole springs of fresh thyme on top and drizzle olive oil over all of this.
Roasts these in the oven at 350°F for about an hour. The tomato skins should be wrinkled and the vegetables soft but not mushy. Let them cool long enough to be able to squeeze out the flesh of the garlic cloves which will infuse the aioli sauce with an abundance of flavor.
Step #2 – Purée in the Food Processor
Once the roasted vegetables are cooled, blend them in the food processor with all the other ingredients. Process the mixture until smooth scraping down the bowl in between pulsing. That’s it. So simple. So easy.
It’s really good if you let it chill and set overnight as all the flavors will meld together. But honestly, there are times I just cannot wait or I haven’t planned ahead. I promise the sauce is still good without the refrigerated time.
What do you serve the sauce with?
This Roasted Tomato and Garlic Aoili sauce is wonderful with so many dishes. It’s perfect with french fries, drizzle it on fish tacos, mix it with pasta, spoon it over an omelet, and wherever else your imagination can take you. My favorites are found here below: Spicy Skewered Chicken (coming soon to my blog) and Sweet Potato Fries or my Smoky Grilled Sweet Potato Rounds.
How Long will this keep in the Fridge?
It’s so hard to believe that this Aioli Sauce will be around for more than a day, but in case you do have leftovers, store it in an airtight container and put it in the fridge. It will last for a week.
