SERVING SUGGESTIONS
Healthy side ideas:
- A large green salad with lemon vinaigrette for a low calorie, fresh side.
- Steamed broccoli or green beans for fiber and vitamins.
- Cauliflower rice for a low carb option.
For a heartier plate, add a small scoop of brown rice or whole grain pasta. For a diabetic-friendly meal, focus on non-starchy sides and control portion size of any grains.
VARIATIONS
-
Healthier version:
- Use low-sodium cream of mushroom soup or make a quick healthy version by mixing low-fat milk with a tablespoon of flour or cornstarch and sautéed mushrooms until thick. Use low-sodium onion soup mix or homemade onion powder, salt, and herbs. This lowers sodium and fat and makes the stew a lighter option.
-
High-protein or low-carb version:
- Increase beef to 2 1/2 pounds or add cubed cooked chicken breast for more protein. For a low carb meal, skip any starch sides and serve with cauliflower rice or roasted non-starchy vegetables. You can also replace the canned soup with beef broth thickened with a small amount of xanthan gum or arrowroot to keep carbs low.
-
Air fryer or oven-baked version:
- While this is a slow cooker recipe, you can adapt it. Sear beef cubes in a hot skillet, then place in an oven-safe dish with mushrooms and onions. Bake at 325°F for 1.5 to 2 hours until tender. For mushrooms with a crispy edge, toss them in a little oil and roast in the air fryer at 375°F for 8–10 minutes, then stir into the stew at the end.
These variations let you make the dish diabetic-friendly, low carb, or higher in protein based on your needs.
