- Yellow Onions: Yellow onions are sweet and pungent with a mild flavor. When sautéed, they become soft and golden, adding sweetness and aroma to the dish.
- Garlic Powder: Garlic powder provides a convenient way to incorporate the flavor of fresh garlic without the need for chopping or mincing. It adds a savory and aromatic element to the dish, enhancing the overall taste.
- Sea Salt and Black Pepper: These seasonings are fundamental for enhancing the flavors of the dish. Sea salt adds a clean, briny flavor, while black pepper provides a subtle heat and depth of flavor.

- Long-Grain Brown Rice: Long-grain brown rice has a nutty flavor and chewy texture. It provides a wholesome base for the dish and offers fiber and nutrients.
- Green Onion: Green onions, also known as scallions, have a mild onion flavor with a hint of freshness. They are used as a garnish for the rice, adding a pop of color and a subtle onion flavor.

How to make Instant Pot Rustic Mushroom Rice
Select the “Sauté” function and the “high” setting on the Instant Pot®. Add two tablespoons of olive oil, onions, and half the garlic powder. Season with salt and black pepper to taste, and stir to combine. Cook, stirring occasionally, until the onions soften, approximately 4-5 minutes.
Add mushrooms and season with remaining garlic powder, and additional salt and black pepper, if desired. Sauté, stirring occasionally, until the mushrooms are golden brown and start to release their liquids, approximately 5 minutes.
Add the Marsala wine and thyme. Cook, stirring occasionally, until the wine is reduced by half and the strong aroma dissipates approximately 4-5 minutes. Transfer sautéed mushrooms and onions to a bowl and set aside.
Add another tablespoon olive oil and one-quarter cup vegetable broth to the Instant Pot®. Gently scrape up any browned bits off the bottom with a wooden spoon.
Add the rice and toast, stirring occasionally, for 1-2 minutes.
Add the remaining broth and stir to combine. Cover and lock lid into place. Set valve to “Sealing” and select the “Manual” and “High Pressure” settings. Adjust cook time to 22 minutes.
Once cook time is complete, allow pressure to release naturally for 10 minutes, then do a quick release for any remaining pressure.
Carefully remove the lid and fluff the rice with a fork. Add the mushroom mixture to the Instant Pot®. Add the green onion and parsley and stir to combine.
Turn off the Instant Pot® and transfer the rice to a serving dish. Serve immediately with your choice of entrees.
