Tender slow-cooked beef pot roast tucked into warm tortillas and topped with crisp garnishes is a total weeknight winner in my house. These pot roast tacos offer the savory comfort of a classic roast with all the fresh vibrancy of taco night. Set up your slow cooker in the morning and come home to melt-in-your-mouth beef just waiting to be piled high with toppings.
I first whipped these up during a chilly fall Sunday and my family devoured them. Now it is our go-to for low-effort gatherings or whenever we want both comfort food and a little party vibe.
Ingredients
- Beef chuck roast: This cut becomes unbelievably tender in the slow cooker and shreds beautifully. Opt for well-marbled meat for the juiciest results
- Kosher salt: Essential for seasoning the meat deeply. Look for salt flakes which dissolve easily
- Black pepper: Brings a gentle heat. Freshly cracked gives more flavor than pre-ground
- Vegetable oil: High smoke point for effective browning without burning
- Yellow onion: Sliced for sweetness and a silky texture in the sauce. Look for firm onions without soft spots
- Garlic: Minced for aromatic depth. Use fresh cloves over jarred for the best flavor
- Beef broth: Forms the base of the braising liquid. A low-sodium option gives you more control over salt
- Diced tomatoes: Canned tomatoes add juiciness and a tangy background note. Check for quality cans with rich color and no metallic smell
- Tomato paste: Adds richness and body
- Chili powder: Ground blend for warmth and complexity. Choose a fresh vibrant smelling chili powder
- Ground cumin: Infuses the beef with earthiness and subtle spice
- Smoked paprika: Gives a smoky flavor pop. Spanish smoked paprika adds the most aroma
- Dried oregano: Brings an herbal slightly citrusy note
- Cayenne pepper: Optional for those who want a little heat
- Corn or flour tortillas: Soft vessels for taco filling. Search for pliable tortillas either fresh or from a trusted brand
- Shredded lettuce: For a crisp cool topping
- Diced tomatoes: Brings freshness and juiciness
- Fresh cilantro: Lifts everything with a hit of green and citrus flavor
- Queso fresco or shredded cheddar: Creamy contrast if desired. Try to get a block and crumble yourself
- Pickled red onions: Optional but their tangy crunch cuts richness
- Lime wedges: Finishing squeeze brightens every bite
Instructions
- Sear the Beef:
- Pat the chuck roast fully dry and season all over with the salt and black pepper. In a large skillet add vegetable oil and heat over medium high until shimmering. Sear the beef on each side for three to four minutes until richly browned. This step locks in flavor and sets up the best texture
- Layer into the Slow Cooker:
- Transfer the seared beef directly into the slow cooker. Scatter the sliced onions and minced garlic over the top ensuring the aromatics cover the beef pieces well
- Mix and Pour the Marinade:
- In a mixing bowl whisk together the beef broth diced tomatoes with their juices tomato paste chili powder cumin smoked paprika oregano and cayenne if using. Blend until smooth then pour over beef in the slow cooker so everything is immersed in the sauce
- Slow Cook to Tender Perfection:
- Cover the slow cooker and set on low for eight hours. The beef is ready when it pulls apart easily with a fork and the liquid is rich and slightly thickened
- Shred the Beef:
- Using tongs remove the beef to a cutting board. Shred gently with two forks separating the strands and discarding any large fatty pieces. Skim excess fat from the cooking liquid remaining in the slow cooker
- Combine and Keep Moist:
- Return the shredded beef to the slow cooker and stir into the saucy mixture. This keeps the meat juicy and flavorful until serving
- Warm the Tortillas:
- Wrap tortillas in a damp towel and microwave in short bursts or toast in a dry skillet until soft and pliable
- Assemble the Tacos:
- Spoon a generous amount of shredded pot roast into each tortilla. Top with lettuce diced tomatoes cilantro cheese pickled onions if using and finish with a squeeze of lime. Serve immediately and enjoy family style

I absolutely love smoked paprika in this recipe because it reminds me of the way my grandfather used to sneak a pinch into everything. It turns a humble pot roast into something dinner guests rave about. My family always fights for the crispiest edge pieces to pile onto their tacos.
Storage Tips
Store leftover beef and toppings separately in airtight containers in the fridge for up to four days. Reheat shredded beef gently in a skillet with a splash of extra broth or water to keep everything moist. If you have extra tortillas keep them wrapped in their packaging or in foil to prevent drying out
Ingredient Substitutions
You can use pork shoulder or boneless short ribs if beef chuck is unavailable. Brown sugar or a drizzle of honey adds a hint of sweetness if your tomatoes are a little tart. Swap out queso fresco with avocado for a dairy free and creamy boost
Serving Suggestions
Serve these tacos with a simple cabbage slaw or a side of Mexican rice for a heartier meal. Fresh salsa verde or your favorite hot sauce are delicious drizzled over the finished tacos. Let everyone build their own for a fun taco bar atmosphere
Cultural Context
