Heat your oil or butter in a large skillet or pot.
Medium heat works best. You want a gentle sizzle, not a grease fire.
Add diced onion.
Cook until soft and slightly golden, about 4–5 minutes. Stir occasionally so nothing burns.
Add minced garlic.
Cook for 30 seconds. That’s it. Garlic burns fast, and burnt garlic ruins everything.
Add the green beans.
Toss them in the onion-garlic mixture so they’re lightly coated. Let them sauté for 2–3 minutes.
Pour in broth.
Add just enough to partially cover the beans. You’re simmering, not drowning them.
Season boldly.
Add smoked paprika, salt, pepper, and a tiny pinch of sugar if needed. Stir well.
Simmer gently for 20–25 minutes.
Cover and cook until beans are tender but not mushy. Stir occasionally and check liquid levels.
Adjust seasoning before serving.
Taste and tweak. Add a pinch more salt or paprika if needed.
