Transforming tough cuts of meat into tender, melt-in-your-mouth dinners is the magic of the slow cooker. This round steak pizzaiola captures classic Italian-American comfort in a simple, hands-off dish that requires only minutes of active preparation time to assemble.
Pizzaiola-style cooking traditionally involves braising meat in a tomato-based sauce seasoned with oregano and garlic. By utilizing the slow cooker, this version achieves a depth of flavor that usually requires hours of stovetop monitoring.
This recipe is designed for those who appreciate a hearty meal that develops its complexity while the day goes by, resulting in a dish where the steak becomes incredibly tender and the sauce takes on the savory essence of the mushrooms and onions.
Ingredients
Main Ingredients
- 2 lb round steak, cut into palm-size pieces
- 8 oz mushrooms, sliced
- 1 medium onion, sliced
Seasoning
- 1 tsp dried oregano
- 1/2 tsp garlic powder
Sauce
- 24 oz marinara sauce
Why this recipe works
The slow cooker method provides a gentle, consistent heat that breaks down the connective tissues in round steak over several hours. This gradual process transforms a naturally lean and tougher cut into a succulent piece of meat that flakes apart with a fork, while simultaneously preventing the steak from drying out as it might with high-heat cooking methods.
By layering the ingredients and covering them with marinara, the sauce acts as a braising liquid. As the steam circulates within the sealed vessel, the aromatics from the oregano, garlic, onions, and mushrooms infuse the meat.
This self-basting environment ensures that every bite is saturated with flavor, creating a cohesive, delicious meal without the need for constant attention.
Notes and substitutions
Round steak is the ideal choice for this recipe due to its lean nature and ability to withstand long, slow cooking. If round steak is unavailable, chuck roast or sirloin tip steak can be substituted with excellent results.
Ensure that whatever cut is selected, it is trimmed of excess fat and cut into uniform pieces to ensure that all portions cook at the same rate.
While the recipe calls for standard marinara, the quality of the sauce significantly impacts the final dish. Choose a marinara that features simple, high-quality ingredients like tomatoes, olive oil, and herbs.
The slow cooker will intensify the sauce, so avoid overly salty varieties. Equipment-wise, any standard 5-to-6 quart slow cooker will work perfectly for this quantity of ingredients.
