Peel and slice the red onions into thin rings using a sharp knife or a mandoline for uniform slices.
Place the sliced onions into a large bowl or a mason jar that can accommodate the volume comfortably.
In a medium-sized bowl, whisk together the apple cider vinegar, extra virgin olive oil, salt, pepper, and red pepper flakes.
Crush the garlic cloves with the side of a knife and add them to the mixture. Stir in the fresh thyme leaves, ensuring that the thyme is evenly distributed in the marinade.
Pour the marinade over the onions, ensuring that they are fully submerged. If you're using a mason jar, you might need to gently press the onions down to cover them completely.
Seal the container with a lid or cover the bowl with plastic wrap.
Allow the onions to marinate at room temperature for at least 30 minutes. For best results, refrigerate and let them marinate overnight to absorb the flavors completely.
Serve the marinated onions as a condiment for salads, grilled meats, or burgers. They can be stored in the refrigerator for up to 2 weeks.
