A garlicky mushroom couscous is a quick and flavorful meal perfect for busy weeknights. Made easily in the Instant Pot, it combines savory mushrooms and fragrant garlic for a comforting, satisfying dish.
Ingredients
- 1 tablespoon butter
- 1 clove garlic, minced
- 1 ¼ cups water
- 8 ounces pearl (Israeli) couscous
- 1 teaspoon garlic base (such as Better Than Bouillon® Roasted Garlic Base)
- ½ cup sliced portobello mushrooms
Step 1
Turn on your Instant Pot and setting it to the sauté mode. Melt the butter, then toss in the garlic and cook it just until you can really smell that lovely aroma, about a minute or so. Pour in the water, add the couscous and the garlic base, then give everything a good stir to mix it all together. Seal the lid and set the pot to high pressure for 5 minutes. It’ll take about 10 to 15 minutes for the pressure to build up.

Step 2
When the cooking time is up, carefully release the pressure using the quick-release method. Once it’s safe, open the lid and fluff the couscous with a fork. Add the sliced mushrooms, then switch back to sauté mode and stir everything together for a few minutes—just long enough to warm the mushrooms without making them soggy.
Frequently Asked Questions
Can I use regular couscous instead of pearl (Israeli) couscous?
Regular couscous cooks faster and has a different texture, so cooking times and water amounts will need adjustment.
Do I need to soak the couscous before cooking?
No, the couscous cooks directly in the Instant Pot with the water and garlic base.
Can I add other vegetables besides portobello mushrooms?
Yes, feel free to add vegetables like spinach or bell peppers, but add them after pressure cooking to avoid overcooking.
How do I prevent the garlic from burning during sauté?
Cook the garlic only until fragrant, about one minute, and stir frequently to avoid burning.
Can I use chicken broth instead of water?
Yes, using chicken broth will add more flavor to the dish.
Is it okay to use dried mushrooms instead of fresh?
Fresh mushrooms are best for texture, but you can rehydrate dried mushrooms first and add them after cooking.
Can I double the recipe?
Yes, but make sure not to fill the Instant Pot more than half full to allow proper pressure cooking.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 3 days and reheat gently.
