Cottage Pie with Mashed Cauliflower Topping

Each time I post a recipe for this type of pie, people seem to love to discuss the differences between cottage pie and shepherd’s pie.  Beef is typically used in cottage pie and ground lamb in shepherd’s pie.  In my kitchen cooking is about fun and family and not getting too terribly troubled by such things. I usually make them both with ground beef since ground lamb is more pricey and not as readily available. This Cajun spice in this beefy cottage pie is a nice twist on flavors adding a bit of heat but, it’s not overwhelming.

Lower Carb Mashed Cauliflower Seals the Deal

While I certainly don’t think that mashed cauliflower tastes just like mashed potatoes but, it’s pretty darn close. I whip them using my hand mixer which leaves a bit of texture that we really enjoy.

  • If you’re a stickler for texture quality and prefer them to be completely smooth, you’ll need to puree the cooked cauliflower using a food processor.
  • The dairy products in this dish can be substituted with lighter versions too, with great results.
  • I often assemble the entire cottage pie in advance then cover with plastic wrap and chill until I’m ready to bake it.
  • When assembling in advance, bring to room temperature prior to baking by allowing it to sit on the counter for 20 minutes. If there’s no time, increase the baking time by 10-15 minutes and bake until heated through and it’s golden on top.

One other thing I love about this dish is; it’s a one dish meal incorporating meat, vegetables with a creamy mashed cauliflower topping hitting all the flavor points we love. Other lower carb options to try is my Cheddar Cauliflower Soup with Bacon and Cauliflower Deep Dish Pizza from Sugar Free Mom.
