Ingredients Needed to Make Keto Ground Beef and Tomato Casserole

Why Use RO*TEL® Diced Tomatoes & Green Chiles?
Please note that this post is NOT sponsored by RO*TEL®. I just used their canned diced tomatoes and green chiles in this recipe because they make this casserole a zillion times easier to get on the table. They’re full of flavor, and they make throwing this casserole together incredibly easy.
I typically pick them up at Walmart, but you can also find them at Target and most grocers in the U.S. If you can’t find them or are located outside of the U.S., you can use 12 oz diced tomatoes and add additional seasoning to the casserole to taste.
You can also get them on Amazon:

How many servings or what is size of single serving
Hi Laurie! This recipe makes four servings.
Wish there was still dates at the top of the post!!!
What I wanted to say was Salsa added to the casserole works when you do not have Rotel!
Hi Becky! I removed the dates because people would see an “old” date and think the post was outdated 🙁 I published this one back in February of this year.
Thank you so much for the feedback of salsa as a Rotel sub – that is a GREAT idea! I’ll definitely have to give it a try.
What would you recommend as sides to go with this?
Hi Katie! I find this to be a pretty complete meal. If you wanted to add a small side, you could do a side salad with a keto salad dressing from this list.
We found this to be very good. I did make some changes to the recipe though. I added onions with the ground beef while cooking and added softened cream cheese to the sour cream mix to make it creamier. I served it with cilantro lime cauliflower rice.. Will definitely make again.
Hi Lisa, Yum! Your changes sound delicious. Thanks so much for giving my recipe a try and for leaving a review!
What size cans of Rotel do you use..10oz or larger?
Hi Carolyn! I use the 10oz can size.
This recipe for Keto Ground Beef and Tomato Casserole is good for the times you want to just quickly put together a meal without a lot of fuss. I prefer using the mild ROTEL Diced Tomatoes.
I need Keto friendly meals that my children will eat and also will work for me on Keto. I tried your cheesy Keto ground beef casserole last night and am happy with the results. I used the mild version of Rotel diced tomatoes & green chilies because my kids don’t like a lot of spice. I served a side salad of greens with the Keto ranch dressing and gave the kids some carrot sticks and broccoli to dip in the ranch dressing. I am loving your Keto casserole recipes!
Can you use chicken instead of ground beef?
Hi Jenny! Yes, you can use ground chicken instead.
it was delicious. I doubled the recipe for 9×13 pan. Used diced tomatoes and little extra cheddar cheese. My keto friends loved it.
Great recipe and easy to make!
Recipe calls for full can of rotel in the meat. Then remaining rotel to sour cream.
Hi Tammy, Yes! That is correct. One can goes in the meat, then the remaining 1/2 can goes in with the sour cream.
