Pat pork chops dry. Season both sides with salt, pepper, and paprika.
Heat olive oil and half the butter in a large skillet over medium-high.
Sear pork until golden, 3–4 minutes per side. Transfer to a plate.
Lower heat to medium. Melt remaining butter, then sauté garlic for 30 seconds.
Pour in chicken broth and scrape up browned bits. Simmer 2 minutes.
Stir in heavy cream, Italian seasoning, Dijon, and red pepper flakes. Simmer until slightly thickened, 3–4 minutes.
Whisk in Parmesan until smooth. Taste and adjust seasoning.
If sauce seems thin, mix cornstarch with water and whisk in. Simmer 1 minute to thicken.
Return pork to the pan. Simmer gently until cooked through, 3–5 minutes, or 145°F inside.
Fold in spinach to wilt. Remove from heat and sprinkle with parsley.
