Season the beef pot roast generously with salt, pepper, and either Italian or taco seasoning. Make sure to coat all sides to infuse every bite with flavor.

Sear the beef in a large pot over medium heat, adding a splash of oil. Brown the meat on all sides, creating a rich crust for about 4-5 minutes until golden brown.

Combine the canned tomatoes and tomato paste into the pot, stirring well to blend all ingredients together. The mixture should be hearty and inviting.
-
Cover the pot and reduce the heat to low, allowing the beef to cook gently for several hours, around 6-8 hours, until the beef is fork-tender.
