Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

2 lbs chuck roast, cut into chunks
1 zucchini, sliced
1 cup cherry tomatoes
1 cup corn kernels
1 red bell pepper, chopped
1 onion, chopped
3 garlic cloves, minced
2 tablespoons tomato paste
1 teaspoon smoked paprika
Salt and pepper to taste
1 tablespoon olive oil
1 cup beef broth
Fresh basil and thyme

Directions

I start by searing the beef chunks in olive oil until they’re browned and flavorful.
Then I transfer the beef into the slow cooker and stir in the onion, garlic, smoked paprika, and tomato paste.
Next, I add all the vegetables and pour the beef broth over everything.
I season it well with salt, pepper, and a generous handful of fresh basil and thyme.
I cover and cook on low for 7–8 hours or high for 4–5 hours, depending on my schedule.
Right before serving, I give it a good stir and top it off with a few more fresh herbs for a final pop of flavor.

Servings and timing

This recipe serves 6 and takes about 7 hours and 20 minutes total. I spend just 20 minutes on prep, then let the slow cooker handle the rest.

Variations

When I want to change things up, I:

Swap zucchini for yellow squash or green beans for more crunch.
Use brisket or boneless short ribs instead of chuck roast for a different cut of beef.
Add a splash of red wine or balsamic vinegar to deepen the flavor.
Stir in cooked quinoa or couscous during the last hour for extra texture.
Toss in baby spinach near the end for some leafy greens.

storage/reheating

Leftovers are where this dish shines. I store mine in airtight containers in the fridge for up to 4 days. It also freezes well—perfect for meal prep. When I’m ready to reheat, I use the stovetop or oven to keep the texture intact and add a splash of broth or tomato sauce if it needs moisture. I try to avoid the microwave since it can make the veggies soggy.

FAQs

What makes a beef casserole suitable for summer?

I keep it summer-friendly by using light, fresh ingredients like zucchini, bell peppers, and cherry tomatoes. A splash of lemon juice or vinegar cuts through the richness, and fresh herbs give it a brightness that feels right for the season.

Can I make summer beef casserole in a slow cooker?

Yes, and it’s my favorite way to do it. The slow cooker lets me build deep flavor without heating up my kitchen. It’s easy, low-maintenance, and the beef turns out perfectly tender every time.

What vegetables go best in a summer beef casserole?

I always reach for zucchini, corn, tomatoes, bell peppers, and green beans. These veggies hold up well in the slow cooker and add lots of color and natural sweetness.

How long should I slow cook beef for a tender casserole?

For the best results, I cook it on low for 7–8 hours or high for 4–5 hours. That gives the meat enough time to break down and become fork-tender.

Can I use the leftovers for other meals?

Absolutely. I love stuffing the leftovers into baked potatoes, wrapping them in tortillas, or turning them into beefy nachos. They even taste better the next day, and I always freeze a portion for an easy future dinner.

A Slow Cooked SUMMER Beef Casserole brings all the heartiness I crave without the heaviness I try to avoid during warm months.
