How to Make It

Add remaining 1 tablespoon oil, rice, and 5 cups water to cooker, scraping cooker to loosen browned bits. Turn cooker off.
Close and lock the lid of the Instant Pot®. Turn the steam release handle to "Sealing" position. Press [Manual]; select "High Pressure," and use [-] or [+] to choose 8 minutes pressure cooking time. When time is up, turn cooker off. Open the cooker using Quick Pressure Release (page 4). While rice mixture cooks, place onion in a medium bowl. Add cold water to cover; let stand 10 minutes. Drain.
After pressure is released, stir broccoli into rice mixture in cooker; let stand 30 seconds. Drain broccoli mixture through a fine sieve; rinse with cold water, and drain well.
