Why We Love This
Everybody has their favorite version of Mexican rice casserole. This one is our favorite because it’s full of flavor and always turns out perfect. It’s versatile, too. Everybody can add their own toppings so everybody is perfectly pleased. Making this for Cinco de Mayo is a tradition but any day is a great day for making this easy Mexican dinner recipe! And it qualifies for a Taco Tuesday meal.
Ingredients and Substitutions
Ground Beef – you could use ground turkey if that’s your preference
Onion, Bell Pepper, and Celery – use the convenient frozen chopped “seasoning blend”
Salsa – pick your heat level, chunky or smooth. Use a can of tomatoes if preferred
Black Beans – use pinto beans if that’s what you already have
Southwest Corn – this canned corn adds more flavor than plain whole kernel corn
Red Enchilada Sauce – any store-bought brand is fine. Choose mild, medium, or hot
Butter – need I say more?
Chili Powder – gives this dish a slight kick and smokey flavor (try smoked paprika for a change of pace)
Ground Cumin – found in many Mexican dishes, it gives a warm, peppery flavor. Use coriander if you need a substitute
Minced Garlic – use powdered garlic you already have that on hand but the jarred kind sure is good and handy, too
Onion Powder – love this basic pantry staple but you can use onion flakes if that’s all you have on hand
Oregano – use dried thyme if you don’t have oregano
Cumin Seed – add great flavor but you can certainly leave it out if you want to
Black Pepper – love this basic pantry staple – fresh ground is best
Long Grain White Rice – Long grain white rice won’t get mushy or stick together like regular rice does. You can use brown rice instead but you will likely need to let this cook longer, perhaps as much as one additional hour, so please adjust the time as needed.
Lime – adds special zing as a final touch
Brown the ground beef and drain. Add to your crock pot.
Add remaining ingredients (except the lime).
Mix well and cook on high for 3 hours or low for about 5 hours (or until rice is cooked).
Spoon into a serving bowl and top with a squeeze of lime. Add more of your favorite toppings such as shredded cheese, sliced avocado, sour cream, green onions, etc. Serve with chips or use as a filling for tortillas.
Every time I use the crock pot for my favorite slow cooker recipes, I always ask myself, “why don’t I use this crock pot more often!” I’ve had this crock pot for at least 5 years. It’s not fancy, but I love it.
The crock pot, also known as a slow cooker, is simply a magical meal maker! There’s something special and delicious about a meal that’s been slow cooked all day. This crock pot Mexican casserole is perfect for an easy meal any day of the week. Here’s the before picture.
Best Time-Saving Tip
Have you tried the frozen chopped onion, bell pepper, and celery blend? I tell you that this stuff is the only way for me. Once I discovered this, I have yet to chop another onion (and I have not shed any tears since!). Some people may gawk at the idea of using this, but if fresh onions and bell peppers are your thing, then continue to chop, chop, chop. Fresh is better, I won’t even try to convince you otherwise. But in my world, the pre-chopped, frozen version works for me!
What are the Benefits of a Crock Pot ?
- Superior at tenderizing tougher cuts of meat. Besides you can set it and forget it, there are many benefits of a crock pot! Let’s explore them:
- The crock pot will do all the cooking while you’re asleep or away from your home.
- Only two pots to clean! One pot to cook the ground beef, and the other pot being the slow cooker.
- It’s convenient to take to the office or another person’s home…just plug it up to reheat (or keep hot) that delicious food you just made.
- Slow cooking brings out more flavor most of the time.
- Your crock pot will use much less electricity than your oven or stove.
Who Invented the Crock-Pot?
The crock-pot was invented by Irving Nachumsohn in 1940! He invented the slow cooker to cook a Jewish stew that is eaten on the Sabbath. He wanted to cook it the day before the Sabbath but it was prohibited for Jews to cook on the Sabbath. So he invented the crock pot to cook it the day before! Here’s the entire article from One Country, A Brief History of Crock-Pot, The Original Slow Cooker.
How to Serve
Now, you can enjoy this Mexican casserole as is, right out of the crock pot when it’s done. Spoon it into a bowl, add a squeeze of fresh lime juice and some shredded cheese and enjoy. Add some avocado and sour cream and you’re good to go.
Some people have been known to eat this casserole with tortilla chips or corn chips. Try it inside a taco shell. Others have used this casserole as a filling for their wraps. I’m always interested to hear how creative people can be with food! This is truly an easy dinner meal. Now, let’s get crocking!
This casserole freezes well. Allow it to completely cool off. Then place into a freezer container or sealable plastic freezer bag (write the date on the bag so you can easily remember it). It will stay fresh for up to 3 months. Thaw in the fridge the day before you plan to eat if. Reheat in a pot on the stove or in the microwave.
Store any leftovers in airtight containers in the refrigerator for up to 3 days. I prefer to use BPA-free glass containers with locking lids. Check out this 18-piece set of glass food storage containers with locking lids from Bayco, available now on Amazon.
