FAQs
CAN I USE FROZEN MEATBALLS INSTEAD OF MAKING MY OWN?
YES, YOU CAN DEFINITELY USE FROZEN MEATBALLS TO SAVE TIME. JUST ADD THE FROZEN MEATBALLS STRAIGHT INTO THE CROCKPOT AND POUR THE FRENCH ONION SOUP OVER THE TOP. COOK THEM ON LOW OR HIGH UNTIL THEY ARE HEATED THROUGH AND TENDER, MAKING SURE THEY’RE HOT IN THE CENTER BEFORE SERVING. THIS SHORTCUT IS PERFECT FOR BUSY DAYS OR WHEN YOU’RE COOKING FOR A CROWD.
CAN I MAKE THIS RECIPE AHEAD OF TIME?
ABSOLUTELY! YOU CAN MIX AND SHAPE THE MEATBALLS A DAY IN ADVANCE AND STORE THEM COVERED IN THE REFRIGERATOR. THE NEXT DAY, JUST POP THEM INTO THE CROCKPOT, POUR OVER THE FRENCH ONION SOUP, AND LET THEM COOK. YOU CAN ALSO COOK THE MEATBALLS COMPLETELY, COOL THEM, AND REHEAT THEM LATER IN THE SAUCE, WHICH MAKES THIS RECIPE GREAT FOR MEAL PREP OR ENTERTAINING.
WHAT IF I DON’T HAVE FRENCH ONION SOUP?
IF YOU DON’T HAVE CANNED FRENCH ONION SOUP, YOU CAN MAKE A QUICK HOMEMADE VERSION. USE BEEF BROTH AS A BASE AND ADD SAUTÉED OR CARAMELIZED ONIONS, PLUS A PINCH OF GARLIC, THYME, SALT, AND PEPPER TO MIMIC THAT CLASSIC FRENCH ONION FLAVOR. POUR THIS MIXTURE OVER THE MEATBALLS IN THE CROCKPOT AND COOK AS DIRECTED. IT WON’T BE IDENTICAL TO THE CANNED SOUP, BUT IT WILL STILL BE RICH, SAVORY, AND DELICIOUS.
