Ingredients
  

  • 2 large whole onions (yellow or sweet)
  • 4-6 cups water or broth
  • 2-4 tbsp butter
  • 3-4 garlic cloves, lightly smashed
  • Salt, to taste
  • Black pepper, to taste
  • Optional flavor boosters
  • 1/2 tbsp paprika or smoked paprika
  • 1/2 tbsp Cajun seasoning
  • 1-2 bay leaves
  • Fresh thyme or parsley

Equipment

  • Medium pot or saucepan
  • Knife
  • Cutting board
  • Measuring spoons
  • Slotted spoon
  • Serving bowl

Method
 

  1. Prepare the onions

    Peel the whole onions and trim the root ends slightly while keeping them intact so they stay together while cooking.

  2. Prepare the cooking liquid

    In a medium pot, add water or broth, smashed garlic cloves, salt, pepper, and optional seasonings like paprika or bay leaves.

  3. Bring to a boil

    Place the pot over medium-high heat and bring the liquid to a gentle boil.

  4. Add the onions

    Carefully add the whole onions to the pot. Reduce heat to medium-low and let them simmer.

  5. Cook until tender

    Simmer for 20–25 minutes until the onions are fork-tender but still hold their shape.

  6. Add butter

    Stir in the butter during the final 5 minutes of cooking so it melts into the broth and coats the onions.

  7. Serve

    Remove onions with a slotted spoon and place in a serving dish.Spoon a little buttery broth over the top and garnish with fresh parsley or thyme.
