Onion: One-Pot Weeknight Recipes

Spice & Simmer keeps 170 recipes that call for onion on hand. This page exists so that when you find onion in your fridge, your cart, or on sale at the store, you can walk straight to a real one-pot weeknight dinner instead of staring at a generic search results page.

Where Onion fits on a weeknight

In our library, onion shows up most often in Beef dishes — a good signal of where it tends to feel most at home on a weeknight plate. You will see it lean into Spanish recipes more than any other tradition, though the ingredient travels well across cuisines. And it pairs naturally with the Skillet & One-Pan technique — that's the cook method most of these recipes use.

How we use onion

Every recipe in this collection treats onion as a real ingredient with a job to do — never as filler, never as a garnish that you could leave out without anyone noticing. We tested each recipe with the ingredient at the center of the dish, swapped substitutions only where they clearly worked, and noted the ones where onion is genuinely the star versus the ones where it's part of an ensemble.

If you bought onion for one specific recipe and have leftovers, scan the cards above for a second use — most of these dinners are designed to clear out a half-used package on the second night, which is the quiet superpower of cooking from an ingredient list rather than a meal-plan list.

Shopping & storage notes

Buy onion when it looks fresh and in season — that's when it's cheapest and tastes the most like itself. For weeknight cooks, the most useful skill is portioning at the moment you bring it home: split the package into recipe-sized portions, label and freeze what you won't use this week, and you've removed the single biggest blocker to cooking from your fridge instead of from a takeout menu. The recipes above are all designed to use a normal portion of onion — no oddly large or specialty quantities.
