Turn everyday cauliflower into a crave-worthy dish that really hits the spot. This mix with mushrooms and spinach packs earthy flavors, lots of garlic, and comes together quickly. It’s my favorite side when I want something filling that doesn’t weigh me down. Found this combo while figuring out how to cut carbs, and now I look at veggie sides in a totally new light.

Last week I made this for my brother-in-law—he usually only wants classic rice. After one plate, he went back for seconds. He had no clue it wasn’t real rice. Here’s the trick: let those mushrooms get deeply browned before mixing in the cauliflower rice.

Tasty Ingredients and How To Choose

  • Coconut Aminos or Soy Sauce: Makes everything taste richer; grab coconut aminos if you need gluten-free
  • Garlic: You can’t beat fresh cloves for flavor—skip the jarred kind if you can
  • Fresh Spinach: You want firm, vibrant green leaves; toss any limp or yellow ones
  • Mushrooms: Pick cremini or button types that feel solid and look dry, not slimy
  • Cauliflower Rice: Both frozen and fresh work great! I usually use frozen since it’s easy and reliable

Choosing good mushrooms makes a difference—they should be dry, hearty, and have that earthy smell. Don’t use mushrooms that feel slimy or look weird. This simple pick makes the finished dish taste way better.

Step-by-Step Cooking Guide

Building Flavors:
Once mushrooms are nicely golden, go in with the minced garlic. Stir until everything smells amazing—this spreads the flavor through the oil. Now put in your cauliflower rice and splash in some soy sauce. Mix so it’s all coated well.
Vegetable Sauté:
Heat up your pan until a drop of water skitters across it. Add oil and diced onions first—let those soften up. Mushrooms go in next. Give them space, so they go brown and don’t just steam.
Cauliflower Rice Process:
If you grabbed frozen, let it thaw and squeeze with a towel to get rid of extra water. Using fresh? Pulse in a food processor till it’s tiny, like rice, then do the same towel trick. This keeps your meal from getting soggy.
Mushroom Preparation:
Wipe mushrooms with a damp paper towel—don’t rinse. Slice them all about a quarter inch thick. I find this size browns up perfectly without going rubbery.

Ingredients

→ Veggie Mix (Fresh & Frozen)

01 2 big handfuls of fresh spinach
02 10 oz of frozen cauliflower rice
03 Half a cup of finely chopped onions
04 A couple of garlic cloves, minced
05 3 cups of sliced mushrooms

→ Kitchen Basics

06 1 tablespoon of olive oil
07 Soy sauce, 1 tablespoon or more if you like extra

Instructions

Step 01

Take that frozen cauliflower rice and cook it like the package says. You want it soft but not mushy—just a little firmness is great.

Step 02

Pour olive oil into a big pan and heat it up until shimmering. Toss in those onions and let them cook until they're nice and see-through, smelling amazing.

Step 03

Throw in the mushroom slices. Let them sit and sizzle until the color turns golden, and all those rich flavors come out.

Step 04

Pop in your minced garlic. Give it a quick mix and cook it just long enough to release the fragrance—don't let it get too dark!

Step 05

Toss the cauliflower rice into the pan. Drizzle soy sauce over it and stir until everything looks well-coated and tasty.

Step 06

Pile spinach on top, and gently work it into the hot rice. Wait a moment for it to wilt and brighten up the dish.
