A slow cooker provides a fuss-free way to make this well-rounded broth, with cauliflower for earthiness, a small tomato for acidic balance and a generous amount of garlic to provide a strong background note.

You'll need a 6-quart slow cooker for this recipe.

The broth can be refrigerated in an airtight container for up to 4 days or frozen for up to 2 months.

Ingredients

measuring cup

Servings: 10  cups

Directions

  • Step 1

    Heat the oil in a large skillet over medium-high heat until the oil shimmers. Add the onions, scallions, carrots, celery and garlic; cook for about 10 minutes, stirring occasionally, until the vegetables have softened and are lightly browned. Stir in 1 cup of water, scraping up any browned bits; transfer to a slow cooker.

  • Step 2

    Stir in the remaining 11 cups water, then add the cauliflower, tomato, thyme sprigs, salt, peppercorns and bay leaves. Cover and cook on LOW for 9 to 11 hours (or for 5 to 7 hours on HIGH). The broth should be deeply flavored and rich.

  • Step 3

    Strain through a fine-mesh strainer without pressing on the solids (which can cloud the broth); discard the solids. If desired, strain again through cheesecloth.

  • Step 4

    Cool to room temperature. Refrigerate for up to 4 days in an airtight container; or freeze flat, in gallon-size resealable plastic food storage bags, for up to 2 months.
