What Goes Into This Recipe – Ingredients

• For the filling:
  • 1 tablespoon olive oil or avocado oil
  • 1 medium yellow onion, finely diced
  • 2 carrots, finely diced (or sub 1 cup diced bell pepper for fewer carbs)
  • 2 celery stalks, finely diced
  • 3 cloves garlic, minced
  • 1 1/2 pounds ground lamb or lean ground beef (90%+)
  • 1 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon black pepper
  • 2 tablespoons tomato paste
  • 1 tablespoon Worcestershire sauce (or coconut aminos for gluten-free)
  • 1 teaspoon dried thyme (or 1 tablespoon fresh)
  • 1 teaspoon smoked paprika
  • 1/2 cup beef or chicken broth (low-sodium)
  • 1 cup frozen peas and carrots mix (optional for stricter low-carb; see Alternatives)
• For the cauliflower mash:
  • 2 pounds cauliflower florets (fresh or frozen)
  • 2 tablespoons butter or ghee
  • 2 ounces cream cheese (or 1/4 cup full-fat Greek yogurt)
  • 1/3 cup grated Parmesan
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon kosher salt, plus more to taste
  • 1/4 teaspoon white or black pepper
  • 2–4 tablespoons heavy cream or broth, as needed
• Finish:
  • Chopped fresh parsley, for garnish
  • Extra Parmesan for a golden top (optional)

Instructions

1. Preheat and prep: Heat oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish or a deep 10-inch skillet that’s oven-safe.
2. Make the mash: Steam or boil cauliflower florets until very tender (about 8–10 minutes). Drain well, then let sit in the hot pot for 2 minutes to evaporate excess moisture.
3. Blend it smooth: Add cauliflower to a food processor or use a potato masher.

   Pulse with butter, cream cheese, Parmesan, garlic powder, salt, pepper, and just enough cream/broth to reach a creamy, thick consistency. Taste and adjust seasoning. Set aside.

4. Sauté aromatics: In a large skillet, heat oil over medium-high.

   Add onion, carrots, and celery. Cook 5–6 minutes until softened and lightly browned. Stir in garlic for 30 seconds.

5. Brown the meat: Add ground lamb/beef, salt, and pepper.

   Cook, breaking it up, until browned and no longer pink, 6–8 minutes. Drain excess fat if needed.

6. Build flavor: Stir in tomato paste, Worcestershire, thyme, and smoked paprika; cook 1–2 minutes to caramelize the paste slightly. Add broth and simmer 2–3 minutes until slightly thickened.

   Fold in peas and carrots if using. Taste and adjust seasoning—this is your flavor insurance.

7. Assemble: Spread the meat mixture evenly in your baking dish. Spoon cauliflower mash on top and smooth with a spatula.

   Use a fork to create ridges for extra browning. Sprinkle a little Parmesan if you want a cheesy crust.

8. Bake: Transfer to oven and bake 18–22 minutes, until the top is lightly golden and the edges bubble.
9. Finish strong: Let rest 10 minutes (crucial for clean slices). Garnish with parsley.

   Serve and bask in the applause.

How to Store

• Fridge: Cool completely, then cover and refrigerate up to 4 days. Reheat at 350°F, covered, for 15–20 minutes, or microwave individual portions.
• Freezer: Wrap tightly and freeze up to 3 months. Thaw overnight in the fridge, then reheat covered at 350°F until hot.
• Meal prep tip: Portion into airtight containers for grab-and-go lunches.

  Add a splash of broth when reheating to keep it silky.

Benefits of This Recipe

• Lower carb, higher satisfaction: Cauliflower mash slashes carbs without sacrificing texture or flavor.
• Protein-forward: Ground meat and cheese keep you full longer and support active lifestyles.
• Nutrient-dense: Veggies bring fiber, vitamins A/C/K, and antioxidants—no sad salad vibes here.
• Budget-friendly: Simple ingredients, big flavor payoff. Leftovers handle lunch like a pro.
• Family-approved: Kid-friendly, partner-friendly, skeptical-friend-who-hates-diets-friendly.

Avoid These Mistakes

• Watery mash: Don’t skip draining and steaming off moisture. Soggy mash ruins the topping and leaks into the filling.
• Under-seasoning: Cauliflower is mild.

  Season both mash and filling generously. Taste as you go.

• Skipping the tomato paste step: Briefly caramelizing paste deepens flavor. Two minutes changes everything.
• Too much liquid in filling: Simmer until slightly thick.

  You want saucy, not soupy.

• Baking immediately after assembly: Give it that 10-minute rest post-bake. It sets and slices beautifully—worth the wait.

Alternatives

• Protein swaps: Ground turkey or chicken for lighter; bison for lean richness; or go half lamb, half beef for balance.
• Dairy-free mash: Use olive oil or ghee and coconut cream, skip Parmesan, and add nutritional yeast for cheesy vibes.
• Keto-tight: Skip peas and carrots; use diced zucchini, mushrooms, or green beans. Keep onions moderate.
• Herb upgrades: Fresh rosemary, thyme, or a splash of red wine vinegar at the end for lift.
• Spice lane: Add a pinch of cayenne or chili flakes to the filling for subtle heat.
• Make it one-pan: If using an oven-safe skillet, build the filling and top with mash right in the pan.

  Fewer dishes FTW.

FAQ

Can I make this ahead?

Yes. Assemble the pie, cover, and refrigerate up to 24 hours before baking. Add 5–10 extra minutes if baking from cold.

Is this gluten-free?

It can be.

Use gluten-free Worcestershire or swap with coconut aminos plus a dash of fish sauce for umami. Everything else is naturally gluten-free.

How do I keep the cauliflower mash from being grainy?

Cook the florets until fully tender and use a food processor or immersion blender. The combo of butter, cream cheese, and Parmesan helps emulsify into a smooth, rich texture.

What if I don’t have tomato paste?

Use double-concentrated tomato paste if available, or simmer an extra 5 minutes with a splash of passata or crushed tomatoes, reducing to thicken.

A little extra paprika boosts depth.

Can I add cheese on top?

Absolutely. A light layer of Parmesan or a sprinkle of shredded cheddar creates a golden crust. Keep it modest if you’re tracking macros.

How low-carb is this?

Exact counts vary by veggies and dairy.

Rough ballpark: 8–12g net carbs per serving if skipping peas/carrots and using keto-friendly swaps. Always calculate with your ingredients, FYI.

My Take

This is the rare “healthy swap” that actually outperforms the original. The cauliflower mash is creamy, the filling is rich and savory, and the whole dish eats like a hug.

It’s weeknight-easy, dinner-party-worthy, and IMO the best way to convert cauliflower skeptics. Make it once and you’ll wonder why mashed potatoes were hogging the spotlight.
