Recipe Tips and Tricks

Cut root vegetables into uniform 1–1.5 inch pieces for even cooking.
Layer dense veggies (carrots, potatoes) on the bottom, delicate ones on top.
Add frozen veggies or greens in the last 30–60 minutes only.
Acidic ingredients (tomatoes, vinegar) go in the last 2 hours to prevent tough beans/skin.
Use the “low and slow” setting for best vegetable texture.
Stir only once or twice—too much stirring creates mush.
Finish with fresh herbs or a pat of butter for restaurant shine.

Ingredients

Bell peppers & zucchini (last 2 hours – keep some bite)

Instructions

Choose your protein and sauce base first.
Cut root vegetables into uniform 1–1.5 inch pieces.
Place carrots, celery, onions, and potatoes directly on the bottom.
Add meat or main protein on top of the root-veg layer.
Pour in liquid (broth, tomatoes, etc.)—but hold acidic ingredients.

Notes

Timing is based on a 6-quart slow cooker—smaller cookers may need 30–60 min less.
Always layer dense → delicate from bottom → top.
Overfilled crockpots cook slower—never fill past the ¾ mark.
