Tips for Making the Best Vegetarian Summer Crockpot Recipes
Here are a few quick tips to help every recipe come out great.
Don’t lift the lid too much. Every time you open it, you lose 20-30 minutes of cook time. Trust the process.
Add fresh herbs at the end. Fresh basil, parsley, or cilantro lose their flavor fast. Always add them in the last 15-30 minutes.
Cut vegetables the same size. This helps everything cook evenly. No one wants mushy onions and raw carrots in the same bowl.
Add dairy near the end. Cream, sour cream, and cheese can curdle if they cook too long. Stir them in during the last 30 minutes.
Use the right size crockpot. Most of these recipes work best in a 6-quart slow cooker. Too small and it overflows. Too large and it dries out.
💡 A 6-quart programmable slow cooker is honestly one of the best kitchen tools you can own, especially for busy summer weeknights.
