When I was growing up, my mom often made Italian‑style green beans simmered in a simple tomato sauce. The beans were cooked until they were incredibly tender—almost melting right into the sauce—and they were one of those comforting side dishes that showed up on the table again and again. I’ve recreated that nostalgic flavor in the Instant Pot, and it works beautifully.
Use fresh, firm green beans — even the larger, more mature ones work beautifully in the Instant Pot because they soften without getting mushy.
Cut out any tough strings or ends on bigger beans so they cook evenly and melt into the sauce.
Add cannellini beans at the end so they stay creamy and don’t break apart under pressure.
Taste and adjust the seasoning once everything is cooked; a pinch of salt or a splash of olive oil at the end can brighten the whole dish.
