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
Why This Recipe Is A Must Try
Quick, flavorful, and comforting. The garlic and mushrooms add a rich, savory taste while the couscous cooks perfectly fluffy in the Instant Pot®. It’s a great option for a busy weeknight or a simple side dish.
Cooking Pointers
- Use fresh garlic and mushrooms for the best flavor.
- Avoid overcooking the couscous to keep it light and fluffy.
- Let the pressure naturally release for a few minutes before opening the lid to keep the texture perfect.
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.
Best Pairings For This Dish
Serve this dish warm alongside grilled chicken, roasted vegetables, or a fresh salad. Garnish with chopped parsley or a squeeze of lemon juice to brighten the flavors.
Leftover Care Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave with a splash of water to keep the couscous from drying out.
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.

Really enjoyed how the garlic and mushrooms balanced each other out. The couscous texture was fluffy and light. Made it on a whim for dinner and it turned out way better than expected. Leftovers were even better the next day.

Was in a hurry and needed something easy—this fit the bill perfectly. The garlic added a lovely depth of flavor without being too strong. I followed the recipe closely but left out the parsley since I didn’t have any on hand, and it still tasted great. Will make again for sure!

The recipe was easy and the texture was good, but I felt it needed a bit more seasoning overall. Added some chili flakes and a squeeze of lemon to brighten it up. My kids liked it though, which is always a win here! Would tweak it next time but still good.

I’ve made this a couple times now and it always comes out well. Sometimes I add a little chili for a bit of heat, which my wife loves. The texture of the couscous was never off, and the mushrooms cooked just right. A quick and tasty dish for busy evenings.

Cooked this for a family lunch and everyone loved it, especially my kids who usually avoid mushrooms. The garlic flavor was just right and the couscous was fluffy and light. I did forget to rinse the couscous first but it still turned out well. Will definitely do again.

I’m new to Instant Pot cooking and this was a great starter recipe. Came out exactly as described—mushrooms were juicy and garlic wasn’t overwhelming, which I appreciated. Took less than 30 minutes from start to finish, which helped on a busy day.
