Blood-Sugar–Friendly Pickled Red Onion Recipe

(Tasty, easy, supports balanced meals — but not a cure for diabetes)

 Description

These quick pickled red onions are tangy, slightly sweet, crunchy, and packed with flavor. They’re a great way to add extra vegetables and antioxidants to meals without extra sugar or calories. They pair with salads, tacos, beans, eggs, and grilled meats.

Ingredients

  • 1 large red onion, thinly sliced

  • 1 cup apple cider vinegar (or white vinegar)

  • 1 cup water

  • 1–1.5 tsp salt

  • 1–2 tsp sweetener (optional: stevia, erythritol, or a small amount of sugar)

  • 1–2 cloves garlic, sliced (optional)

  • 1 tsp peppercorns (optional)

  • ½ tsp turmeric (optional for color + antioxidants)

Instructions

  1. Slice onions as thinly as possible.

  2. Place onions in a clean glass jar.

  3. In a small pot, heat vinegar, water, salt, and sweetener until dissolved.

  4. Add garlic, peppercorns, or turmeric if using.

  5. Pour hot brine over onions until fully covered.

  6. Let cool to room temperature, then refrigerate.

  7. Chill at least 1 hour, but best after 24 hours.

Stores for 2–3 weeks in the fridge.

 Notes

  • For zero added sugar, use stevia or erythritol.

✔ Heart-healthy meal support

  • Onions contain antioxidants associated with cardiovascular health.

  • Using this as a condiment boosts flavor without high-calorie sauces.

✔ Gut-friendly

  • Onions contain prebiotic fibers that support gut bacteria.
