This Horseradish Meatloaf with Caramelized Onions and Sour Cream-Horseradish Sauce is really something special in the meatloaf world, with added flavor from caramelized onions, garlic, horseradish, Worcestershire sauce, and a touch of sour cream mixed into the meat before it’s cooked, and a tasty sauce of sour cream, mayo, and horseradish. But this is not quick and easy meatloaf. This is meatloaf to make on Sunday afternoon when you have time to gently caramelize the onions, mix the ingredients together, mix the sauce, and then enjoy leftover meatloaf for lunch all week.

If you’re not up for that much work for meatloaf, you may want to make what my sister Pam dubbed Kalyn’s Best Meatloaf, a version I made for years with canned mushroom soup and onion soup mix. That was good meatloaf too, back in the day when I used to cook with those kinds of ingredients, but if you have more time, my dad gave the Horseradish Meatloaf two thumbs up!

It was still fine because the sour cream keeps the meatloaf juicy.)

Horseradish Meatloaf with Caramelized Onions and Sour Cream-Horseradish Sauce
(Makes 6-8 servings; recipe adapted by Kalyn from notes copied years ago from a friend’s cookbook, but unfortunately the notes didn’t include the name of the book.)

Ingredients:
2 medium onions, diced into small pieces
2-3 tsp. olive oil (or more, depending on your pan)
1 T finely minced garlic
1 tsp. dried thyme
2 eggs, beaten
1/4 cup light sour cream
3 T cream-style horseradish (not horseradish sauce)
1 T Worcestershire sauce
2 lbs. ground beef (use 10% fat or less for South Beach Diet)
1/2 cup breadcrumbs (use 100% whole wheat breadcrumbs for South Beach Diet; can substitute ground pork rinds or almond meal for a gluten-free, lower carb version)
salt and fresh ground black pepper to taste

Sauce Ingredients:
1/4 cup light sour cream
2 T mayo (use light or regular mayo but not fat free)
2 T cream-style horseradish

Instructions:

Dice onions into small pieces. Heat oil in a large heavy frying pan, add onions, turn heat to low and let onions cook and caramelize, stirring every few minutes, until onions are nicely browned. (This will take 30-40 minutes; don’t rush this step and be careful that onions don’t burn or they will be bitter.) Add garlic and dried thyme and cook about 2 minutes more.

While onions are cooking, put the ground beef in a medium-sized bowl and let it come to room temperature. Mix together beaten eggs, sour cream, horseradish, and Worcestershire sauce. After onions have cooked for 15 minutes, start to preheat oven to 375F/190C.

When onions are done, add bread crumbs and onion-garlic mixture to the meat and season with salt and freshly ground black pepper. Then add egg/sour cream/horseradish/Worcestershire sauce mixture to meat. (Adding this on top of the onions will help cool them so you can handle the mixture.) Wash hands, then use your hands to gently combine until all the ingredients are well-mixed into the meat. Handle the meat as little as possible to get the ingredients mixed.

Spray broiler pan or roasting pan with non-stick spray, then form the meat into a loaf shape and place on pan. If desired, use a butter knife to make criss-cross marks in the top of the loaf.

Bake meatloaf about 1 1/2 hours, or until the meatloaf is nicely browned on the outside and cooked through on the inside. (If you have an instant-read meat thermometer, cook until the internal temperature is 155-160F/68-71C. (It will continue to cook during the 15 minutes resting time.)

Let meatloaf rest 10-15 minutes before cutting. While it rests, stir together sour cream, mayonnaise, and cream-style horseradish to make a sauce to serve with the meat.

This freezes well, and would be great to double the recipe and then freeze individual-serving sizes for an easy grab-and-go lunch.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:

With only 1/2 cup breadcrumbs and two pounds of beef, this is a pretty low-carb and low-glycemic recipe, suitable for many low-carb eating plans. When made with ground beef with 10% fat like I used, this meatloaf is great for phase 2 or 3 of the South Beach Diet. If you’d like to make a version that’s gluten-free and even lower in carbs, you can substitute the bread crumbs for ground pork rinds or almond meal.

  1. Lindi, so glad you liked it. I know what you mean about the breadcrumbs, but I'm not sure it would work without them.

  2. I am late to this party, but this was just perfect. So different from the normal ketchup yuckyness. I will make this again, absolutely!
