    1. Hi Erin, I would brown the beef and onion first on the stovetop, then add all ingredients to the slow cooker and cook on low for 4-8 hours or high for 1 1/2-2 hours. Just be sure to keep an eye on it to make sure it doesn’t dry out! Good luck :)

      1. Hi Nicole, you can try making your own tomato puree, or you can try substituting it with diced tomatoes. We would love to hear how it turns out.

  1. Rarely give 3 stars to recipes from Spendwithpennies. Almost all recipes deserve 5+ stars. However, we thought this dish somewhat bland. I didn’t have tomato sauce so I used purée which isn’t as sweet as sauce. Should have added a bit of sugar. Maybe some red pepper flakes. Or Rotel tomatoes. After a few bites my husband added some diced jalapeños.

  2. I wish I could make myself write down some of the things I make. I make them up, don’t measure when I do. Thanks for the receipes you post. I’ve tried a few and have turned out great.

  3. I want to make this in the crockpot. I saw a previous question regarding that but wondered when you recommend adding the rice, tomatoes etc? At the beginning? Or cook rice separately and add towards the end? Thanks!

  4. used this recipe but did it in my instant pot. Turned out great! Followed almost exactly. Sauteed in instant pot. Drained fat. Dumped rest of the ingredients in. Pressured cooked on high for 4 mins. Natural released for 10. Otherwise didn’t change a thing. (Besides just stirring cheese in at the end)5 stars

    1. Hi Kathy, I was planning on doing this in my instant pot today but I was thinking there might need to be a decrease in liquid?
      Cheers Amy

  5. My family and I really enjoyed this dish! I doubled the recipe. Followed exact recipe with one exception. I didn’t have any rice on hand, so I ordered white rice from a Chinese restaurant (to be delivered. lol) and added the cooked rice at the end of cooking time. I continued cooking an additional 20 minutes, so that the juices would be absorbed into the cooked rice. This recipe is so delicious as is, and so basic that you can adapt it to your own tastes and what you have on hand. Also, I added cheese and red pepper flakes (grated Parmesan, which is my preference) to each plate rather than in the pot. Thank you for sharing, I will definitely be adding this to my dinner rotations.5 stars

  6. I used peppers from my garden, but they weren’t the picture perfect size for a traditional stuffed dish. I also used homemade tomato sauce and garden onions. This was an easy recipe. The only thing I added was a little fresh ground pepper and seasoned salt. I feel like this will make great leftovers and the flavors will enhance as it is refrigerated!5 stars

    1. Hi Christine, I would brown the beef and onion first on the stovetop, then add all ingredients to the slow cooker and cook on low for 4-8 hours or high for 1 1/2-2 hours. Just be sure to keep an eye on it to make sure it doesn’t dry out! Good luck :)

  7. This recipe is phenomenal. So easy and super delicious. I have two toddlers and they both love it too! Thank you for so many delicious recipes. Your website is a favorite of mine and I use it at least once or twice a week. Trying your toffee recipe this weekend!!!5 stars

  8. Made this for the family. The idea was to find a recipe with ingredients we had on hand due to the stay at home order. We had ALL ingredients including the Italian seasoning and it was fantastic!5 stars

  9. I made this tonight for dinner. I had to make the following changes due to stay at home order and this is what I had in the house. Used two red peppers and 1/2 green pepper that had to get used up and added two cans of Rotel tomatoes with green chilies. I think that made it a nice spicy flavor. Getting very creative using food that is in the house. Very good recipe.5 stars

  10. Very good! Made almost as written. Added cinnamon to help with acidity (an old Italian thing) and sharp cheddar to top because that is what I had on hand. Will definitely make again. Thank you.5 stars

    1. I’ve only tried it as written but it should work just fine. You may need to adjust cook time slightly.

  11. I made this as a skillet dish (adding about 1/2 cup of chopped green peppers to the skillet mix and left the other green peppers whole. I then cored the green peppers , halved them and grilled them on my traeger grill to roast and soften them. Then spooned the skillet mixture and cheese on top of the green peppers to heat it all up and melt the cheese. It really turned out very nice!!!5 stars
