How to Make Slow Cooker Stuffed Pepper Soup
Before beginning, cook the ground beef in a skillet on the stove, breaking it up with a spoon. Season it with a little salt and pepper and then drain it well.
- Add everything but the rice and cheese to a 5-quart or larger slow cooker. Cover and cook on low for 6 to 8 hours.
- Remove the lid and add the uncooked instant rice and stir. Cover and cook for an additional 15 minutes or until the rice is tender.
- Serve topped with cheese and enjoy!
What is Instant Rice?
Instant rice is white rice that has been fully cooked and dehydrated and cooks quickly to a tender and fluffy state. It’s a great choice for adding dry to soups and casseroles so you don’t have to cook the rice separately in advance.
Can I Use Regular Rice?
Absolutely. If you use regular long grain rice, it should be cooked separately and stirred into the soup just before serving. If you add cooked rice earlier in the process, the rice will take on an unappealing mushy texture as it continues to cook and absorb additional liquid.
Storage Tips
- Refrigerator – Transfer leftovers to an airtight container and refrigerate promptly. Leftover soups that contain rice should be eaten within 2 or 3 days for the best quality. Rice has a tendency to soak up liquid so add a little additional broth when reheating, as needed.
- Freezer – Soups with rice are not the best candidates for freezing. Instead, omit the rice and transfer the soup to freezer-safe plastic storage bags. After defrosting safely in the refrigerator, you can add the instant rice when reheating the soup as directed in the recipe.
Make-Ahead Stuffed Pepper Soup
To make Slow Cooker Stuffed Pepper Soup for future meals, omit the rice and store as directed above. When ready to serve, cook rice separately and warm the soup through on the stove. Add as much rice as you’d like to each bowl and ladle the warmed soup over the top. This allows you to control the soup to rice ratio and the texture of the rice will be perfect!
