All the comfort of a classic American smothered steak dinner, made completely grain-free, dairy-free, and Whole30 friendly. - Author: Krista Wade - Tags: Recipe, Paleo, Dinner, Gluten-Free, Grain-Free, Low-Carb, Nut-Free, Egg-Free, Beef, Skillet, Mushrooms, Gravy, Cauliflower Mash, One-Pan, Comfort Food, Cube Steak, Celiac-Friendly Smothered steak and mashed potatoes is the kind of dinner that has lived on American kitchen tables for generations. My grandma would have recognized this dish in a heartbeat. The only thing she wouldn't recognize is the cauliflower hiding where the potatoes used to be, and honestly, she probably would have loved it anyway because that gravy is absolutely the star of the show. This is real food made real-food friendly. Cube steaks seared hard in a cast iron skillet, then braised low and slow right in a mushroom and onion gravy that is thick, savory, and deeply satisfying. The garlic cauliflower mash underneath soaks every drop of it up. Nothing about this dinner feels like a compromise, and that is the point. The trick a lot of home cooks miss with cube steak is the sear. You have to get the pan screaming hot, pat those steaks bone dry, and leave them alone. Don't fuss. Let the crust build. That crust is where your flavor starts, and then the braise does the rest of the work for you. --- ## Nutritional Benefits ### Beef: Protein, Iron, and B12 in One Bite - Beef is one of the most bioavailable sources of complete protein and heme iron, the form your body absorbs most efficiently. The USDA notes that a 3-oz serving of beef provides around 25g of protein and meaningful amounts of zinc, selenium, and B12. - Vitamin B12 is found almost exclusively in animal foods and is essential for nerve function and red blood cell production, according to the National Institutes of Health Office of Dietary Supplements. - Choosing grass-fed beef when available may offer a better omega-6 to omega-3 fatty acid ratio compared to conventionally raised beef, per research published in Nutrition Journal (2010). ### Cauliflower: A Genuinely Useful Swap - Cauliflower is low in carbohydrates and provides a solid dose of vitamin C, vitamin K, and folate. One cup of cooked cauliflower delivers about 3g of fiber, per USDA FoodData Central. - As a cruciferous vegetable, cauliflower contains glucosinolates, plant compounds that have been studied for their potential role in supporting cellular health, according to the National Cancer Institute. - Using cauliflower in place of starchy potatoes significantly reduces the glycemic load of this meal while keeping it hearty and filling. ### Bone Broth: More Than Just a Base - Beef bone broth provides collagen-derived proteins including glycine and proline, amino acids that are not abundant in muscle meat alone. - Research published in the journal Nutrients (2019) suggests that collagen supplementation may support joint and skin health, and bone broth is a whole-food source of collagen peptides. - Using a high-quality, sugar-free bone broth as your gravy base adds depth of flavor and nutritional density without any junk ingredients. ### Mushrooms: Underrated Nutritional Punch - Cremini mushrooms are one of the few non-animal dietary sources of vitamin D (when exposed to UV light during growing), and they provide B vitamins including riboflavin and niacin, per USDA FoodData Central. - Mushrooms contain beta-glucans, a type of soluble fiber that research in the Journal of Nutrition and Metabolism (2012) links to potential immune-supporting effects. - They add umami depth to this gravy that makes it taste like it has been simmering all day, even on a weeknight. --- ## FAQs ### What is cube steak and where do I find it? Cube steak is typically a cut from the round or chuck that has been run through a mechanical tenderizer, which creates that distinctive dimpled surface. It's a very affordable cut and you'll find it pre-packaged in the beef section of almost every mainstream grocery store. It's been a staple of budget home cooking for decades for good reason. ### Can I use a different cut of beef? Yes. Thin-cut round steaks, sirloin steaks, or even thinly sliced chuck work well here. Just adjust your braise time slightly based on thickness. Thicker cuts will need more time in the covered skillet to get tender. ### Is arrowroot powder the same as cornstarch? They behave similarly as thickeners, but arrowroot is grain-free and paleo-friendly, while cornstarch is not. You use it the same way: mix it with cold water first to make a slurry, then stir it into your hot liquid. It thickens quickly, so keep stirring and don't walk away. ### Can I make this Whole30 compliant? It already is, as long as you confirm your bone broth and coconut milk have no added sugar or non-compliant ingredients. Read the labels on both. Coconut aminos are Whole30 approved. Everything else in this recipe checks out. ### Can I make the cauliflower mash ahead of time? Absolutely. Make it up to two days ahead and store it in an airtight container in the refrigerator. Reheat it gently in a small saucepan over low heat, adding a splash of coconut milk to loosen it back up. It reheats really well. ### My gravy came out too thin. What do I do? Mix an extra teaspoon of arrowroot powder with a tablespoon of cold water, stir it together until smooth, and add it to the simmering gravy. Let it bubble for a minute or two and it will tighten right up. Always mix arrowroot with cold liquid first or it will clump. --- If this is the kind of dinner you want more of in your real-food rotation, save this one and try it this week.

Classic American comfort food made clean, grain-free, and paleo-friendly without losing a single bit of the soul. - Prep time: 15 min - Cook time: 35 min - Total time: 50 min - Servings: 4 servings ### Ingredients - 4 beef cube steaks (about 5 oz each) - 1 teaspoon sea salt - 1/2 teaspoon black pepper - 1/2 teaspoon garlic powder - 1/2 teaspoon onion powder - 1/2 teaspoon smoked paprika - 2 tablespoons arrowroot powder (for dredging) - 2 tablespoons avocado oil, divided - 1 large yellow onion, thinly sliced - 3 cups cremini mushrooms, sliced - 3 cloves garlic, minced - 1 tablespoon tomato paste - 1 1/2 cups beef bone broth (no sugar added) - 1 teaspoon coconut aminos - 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried) - 1 tablespoon arrowroot powder mixed with 2 tablespoons cold water (slurry) - FOR THE GARLIC CAULIFLOWER MASH: - 1 large head cauliflower, cut into florets (about 6 cups) - 4 cloves garlic, peeled - 2 tablespoons ghee - 1/4 cup full-fat coconut milk (canned, well stirred) - 1/2 teaspoon sea salt - 1/4 teaspoon white pepper - Fresh parsley, chopped, for garnish ### Instructions 1. Pat the cube steaks completely dry with paper towels. Mix the salt, black pepper, garlic powder, onion powder, and smoked paprika together in a small bowl. Season both sides of each steak generously with the spice mix, then dust each side lightly with arrowroot powder and shake off any excess. 2. Heat 1 tablespoon of avocado oil in a large, heavy skillet (cast iron is ideal) over medium-high heat until shimmering. Sear the steaks for 3 to 4 minutes per side until a deep brown crust forms. Work in batches if needed so you don't crowd the pan. Transfer the seared steaks to a plate and set aside. 3. Reduce the heat to medium. Add the remaining tablespoon of avocado oil to the same skillet. Add the sliced onions and cook, stirring occasionally, for 6 to 7 minutes until softened and starting to turn golden. 4. Add the sliced mushrooms and cook for another 4 to 5 minutes, stirring occasionally, until the mushrooms have released their liquid and started to brown. Add the minced garlic and cook for 30 seconds until fragrant. 5. Stir in the tomato paste and cook for 1 minute, letting it caramelize slightly on the bottom of the pan. Pour in the beef bone broth and coconut aminos, scraping up any browned bits from the bottom with a wooden spoon. Add the thyme. 6. Bring the liquid to a gentle simmer, then pour in the arrowroot slurry, stirring constantly. Let the gravy simmer for 2 to 3 minutes until it thickens enough to coat the back of a spoon. 7. Nestle the seared cube steaks back into the skillet, spooning the mushroom gravy over the top. Cover the skillet, reduce heat to low, and let everything cook together for 12 to 15 minutes until the steaks are tender and cooked through. 8. WHILE THE STEAKS FINISH: Bring a large pot of salted water to a boil. Add the cauliflower florets and garlic cloves. Boil for 10 to 12 minutes until the cauliflower is very tender and easily pierced with a fork. 9. Drain the cauliflower and garlic well. Transfer to a food processor (or use an immersion blender in the pot). Add the ghee, coconut milk, sea salt, and white pepper. Process until very smooth and fluffy, scraping down the sides as needed. Taste and adjust seasoning. 10. Spoon a generous portion of garlic cauliflower mash onto each plate. Top with a cube steak and ladle plenty of the mushroom and onion gravy over everything. Finish with fresh chopped parsley and serve immediately. ### Nutrition per serving - Calories: 420 - Total Fat: 22g - Carbohydrates: 18g - Protein: 38g - Dietary Fiber: 5g - Sugar: 6g
