Yes, broths can be made in a slow cooker overnight. The pros include convenience and hands-off cooking, while the cons are longer cooking times and potential for over-extraction of flavors.
Making broth in a slow cooker overnight is a convenient way to extract maximum flavor from bones and vegetables. Here's a step-by-step guide:
Gather Ingredients: Collect your bones (chicken, beef, or vegetable scraps), vegetables (onions, carrots, celery), herbs (parsley, thyme), and spices (peppercorns, bay leaves).
Prepare Ingredients: Roughly chop the vegetables. Roasting the bones and vegetables beforehand can deepen the flavor of the broth.
Combine in Slow Cooker: Place the bones, vegetables, herbs, and spices in the slow cooker.
Add Water: Cover the ingredients with water, leaving about an inch of space at the top of the slow cooker.
Cook: Cook on low for 8-12 hours, or even longer. The longer it simmers, the richer the flavor will be.
Strain: Once cooked, let the broth cool slightly. Then, strain it through a fine-mesh sieve or cheesecloth to remove solids.
Cool and Store: Cool the broth completely before storing it in the refrigerator for up to 4 days or in the freezer for several months.
Pros:
Convenience: It's a hands-off method, allowing you to set it and forget it.
Flavor Extraction: Slow cooking gently extracts maximum flavor and nutrients from the ingredients.
Energy Efficient: Slow cookers use less energy than stovetop cooking.
Cons:
Long Cooking Time: It takes a significant amount of time, typically overnight.
Over-Extraction: Cooking for too long can sometimes lead to a slightly bitter or muddy flavor due to over-extraction of flavors from the bones and vegetables.
Space: Slow cookers take up counter space.
Add a splash of apple cider vinegar to the broth while it's cooking. The acidity helps to draw out more minerals from the bones, resulting in a more nutritious and flavorful broth.
