In a shallow bowl, whisk together flour, Cajun or seasoning salt, and Italian seasoning. Dredge each side of the pork chops in the flour mixture, then set aside on a plate. Reserve the flour mixture.
Heat oil in a large skillet over medium-high heat. Once hot, add the pork chops to the pan, and cook 2-3 minutes on each side. Remove them to a plate. Work in two batches if needed.
Add the onions and mushrooms to the skillet and cook for about 5 minutes, until the onions are translucent and vegetables slightly tender. Add garlic and cook an additional minute.
Add 1 1/2 tbsp of the reserved flour mixture, stir and cook 1 minute.
Carefully stir in broth and cream of mushroom soup until it’s a cohesive mix. Scrape and stir in any solid bits from the bottom of the pan. Allow the mixture to simmer on medium heat for 5 minutes.
Taste and add additional seasonings if desired. Return the pork chops to the skillet, coating them on each side. Cover and simmer for 5-8 minutes on medium-low heat or until the pork chops reach an internal temperature of 145°F. Turn off the heat and rest 3 minutes.
Serve over noodles, rice, or mashed potatoes.
