• 1 1/2 teaspoons kosher salt, plus more to taste
• 1 lb Yukon Gold potatoes, sliced 1/4-inch thick
• 3 carrots, peeled and sliced into rounds
• 4 Tablespoons tomato paste
• 1 (14.5oz) can diced tomatoes with juices

• 1 (15oz) can corn, drained
• 2 teaspoons Italian seasoning
• 1 teaspoon smoked paprika
• 2 teaspoons chili powder
• 1 1/2 cups shredded cheese (optional)

How to Cook It

1. Dice the yellow onion and mince the garlic.
2. Slice Yukon Gold potatoes 1/4-inch thick and peel and slice the carrots into rounds.
3. Warm 1 tablespoon olive oil in a large skillet over medium-high heat.
4. Add the ground beef and diced onion to the skillet and cook until the beef is browned and the onions are soft and translucent.
5. Stir in the minced garlic and 1 1/2 teaspoons kosher salt and cook about 1 minute until fragrant.
6. Transfer the beef and onion mixture to the crock pot.
7. Add the sliced potatoes, carrots, 4 tablespoons tomato paste, the 14.5 oz can diced tomatoes with juices, drained and rinsed black-eyed peas, drained corn, 2 teaspoons Italian seasoning, 1 teaspoon smoked paprika, and 2 teaspoons chili powder to the crock pot and stir gently to combine.

8. Cover and cook on low for 6–8 hours or on high for 3–4 hours, until potatoes and carrots are tender when pierced with a fork.

   

9. Taste and adjust salt and seasonings as needed.
10. If using cheese, sprinkle 1 1/2 cups shredded cheese over the casserole, cover, and cook on high 10–15 minutes until the cheese is melted and bubbly.

Tips for Best Results

• Consistency is key: Slice the potatoes evenly so everything cooks at the same rate and you don’t end up with some mushy and some crunchy.
• Season carefully: Since this feeds a lot, it’s important to season at different steps—season the beef while browning, adjust once everything’s combined, and taste before serving.

• Brighten it up: A dollop of sour cream, a sprinkle of fresh chives or parsley, green onions, or a dash of red pepper flakes really brings a fresh pop to the finished dish, kinda like chili!

Mix-Ins and Substitutions

• Veggie switch-ups: Feel free to toss in bell peppers, mushrooms, or even sweet potatoes if you want a change.
• Bean swaps: Swap black-eyed peas for black beans or pinto beans depending on what you have on hand.
• Dairy-free version: Just skip the cheese, and you still have a satisfying, hearty meal.
• Spice it up: Add sliced jalapeños or top with extra red pepper flakes for a nice heat boost.

Storage and Reheating

Let your crock pot cowboy casserole cool completely before storing. This helps avoid sogginess and keeps it fresh longer. Store in airtight containers in the fridge for up to 4 days.

• For individual portions: reheat covered in the microwave until piping hot, or warm on the stove over medium heat, stirring occasionally. Add a splash of water or broth if it feels dry.
• For larger batches: reheat covered in a 350°F oven until warmed through, or pop it back in the crock pot on low for 1-2 hours.
• Make-ahead: prepare the beef and onions first, mix with the rest (hold the cheese), and store in the fridge for up to 4 days before slow cooking.
• Freezing tip: freeze the uncooked assembled mix (without cheese) in freezer bags for up to 3 months. Freeze flat for easy thawing. Thaw overnight in the fridge before cooking as usual.
• Label your containers with dates, push out extra air before freezing, and add cheese only when reheating or right before serving. Avoid refreezing after reheating for best taste and safety.
