Mongolian Beef served over white rice.

You can find this recipe along with many more in my friend Kelly Kwok’s new cookbook The Asian Slow Cooker: Exotic Favorites for Your Crockpot.

You may already be familiar with Kelly from her popular food blog, Life Made Sweeter. I’ve been a reader of Kelly’s blog for several years. She always has the most gorgeous desserts. But I’m really excited she wrote a slow cooker cookbook. I love using my crockpot and good slow cooker cookbooks are few and far between.

Kelly has taken favorite childhood recipes and adapted them to fit the needs of the busy cook in her debut cookbook.

Lots of times, you think of slow cooker food as being bland and one dimensional, but Kelly’s recipes include ingredients like miso paste, ginger, and Sriracha for lots of depth of flavor.

There are 80 delectable Asian dishes and desserts  all together, plus beautiful color photographs. The recipes can either be made in a crockpot or JUST ONE POT.

The recipes are arranged into 8 chapters:

  • Ditch the Takeout
  • 5 Ingredients or Less
  • One Pot & Skillet Meals
  • Skip the Stovetop
  • Fiery Favorites
  • Meatless Mondays
  • Sensational Desserts
  • Delectable Desserts

There are so many recipes I want to try including Dan Dan Noodles, Beef Chow Fun Stir-Fried Rice Noodles, and Lemon Chicken.

If they are anything like this Spicy Mongolian Beef with Pineapple, they will deserve a place on our regular dinner rotation.

Mongolian Beef has always been one of my favorite Asian dishes but until I tried Kelly’s recipe, I had never made it in a crock pot. It’s made with thin slices of flank steak that are coated in cornstarch and seared briefly in a pan. Then they slow cook with a super flavorful sauce made from soy sauce, hoisin sauce, beef broth, Thai sweet chili sauce, ginger, garlic, and red chili flakes.

I love the addition of pineapple chunks and shredded carrots. The sauce gets super thick and really coats the beef well. You are going to love this slow cooker meal!

  1. Hi Christin Um new to your cooking and recipe sight and found your Yeast rolls recipe, I love Golden Coral yeast roles and yours sound even better, there is one problem though, I don’t own too many small appliances, such as the dough one you mention, so everything I do, that requires remotely anything that the yeast rolls require, I have to do it one-handed as I am left side partial paralyzed. I know it bites and not in a good way, but hey it’s life and I love making home made foods, any ideas?

  2. I’m a diabetic that controls my blood glucose through diet. can you tell me how many carbs are in a serving minus the rice since that’s not allowed anyway.

  3. Step 3 says to add sugar, but sugar is not listed among the ingredients. Should it be added? If so how much?
