AIP Friendly Herb-Roasted Onions with Basil
Roasting onions low and slow — well, hot and steady — transforms them into something almost unrecognizable from their raw, sharp selves. These halved yellow onions go into a 400°F oven brushed with olive oil, turmeric, and ginger, and they come out deeply golden, caramelized at the edges, and genuinely irresistible. A quick glaze of apple cider vinegar and honey gets spooned over halfway through, turning sticky and lacquered by the time the onions are fork-tender. Torn fresh basil scattered over the top at the end adds a bright, herby lift that makes the whole dish feel finished and a little fancy. Following the autoimmune protocol means navigating around nightshades, grains, seeds, and a long list of common flavor-builders — but every single ingredient here clears those hurdles without compromise. The flavor payoff is enormous for how simple the method is, and it comes together in one baking dish with minimal cleanup. Serves four as a side, and honestly, it disappears fast.

4 servings
- 4 medium yellow onions (about 2 lb total), halved through the root end
- 3 tbsp olive oil, divided
- ½ tsp fine sea salt
- ¼ tsp ground turmeric
- ¼ tsp ground ginger
- 1 tbsp apple cider vinegar
- 1 tsp honey
Ingredient noteAIP restricts added sweeteners, but small occasional amounts of unrefined honey are accepted on the protocol; the ~1/4 teaspoon per serving here likely stays within that limited allowance. If you prefer to always avoid honey, please tap it and change its rating to Red.
- ¼ cup fresh basil leaves, torn
For serving
- flaky sea salt, for serving (optional)
Instructions
- 1
Preheat the oven to 400°F (205°C). Arrange the onion halves cut-side up in a single layer in a baking dish large enough to hold them snugly without stacking.
- 2
In a small bowl, whisk together 2 tbsp of the olive oil, the turmeric, ginger, and salt. Brush or spoon the mixture evenly over the cut surfaces of the onions.
