Delicious pork & beef meatballs are added to a crockpot with caramelized onions, herbs & beef broth to make this amazing French Onion Meatball Soup recipe!

One of my favorite things to do is combine two foods I love into one amazing new recipe creation!

Buffalo Taco Spaghetti, and Philly Cheesesteak Frito Pie are just a few of my favorite recipe mash-ups!

Today I have a delicious new recipe mash-up to share, combining meatballs and french onion soup. Together, they make the best meatball soup ever!

The meatballs can be served with the broth, soup style, tossed with egg noodles, or spooned over mashed potatoes.

I tried each version so that I could give my honest feedback on which way to serve it and honestly, I couldn’t pick just one! You seriously can’t go wrong with any of these options!

How do you make Meatball Soup?

For this crockpot meatball soup, start by sautéing the onions, then add them to a slow cooker and make the meatballs.

To make the meatballs, combine sautéed onions and garlic with ground beef, ground pork, breadcrumbs, egg yolks and french onion dip mix. Form into meatballs, then sear on each side.

Add the meatballs to a slow cooker, then add flour to the pan you seared the meatballs in. Combine the flour with the pan drippings from the meatballs, then add white wine, beef broth, Worcestershire sauce and french onion dip mix.

Pour this mixture into the slow cooker with a couple sprigs of fresh thyme and bay leaves.

How long do you cook meatball soup?

The meatball soup should be cooked in the slow cooker for at least 2 hours on high, or 4-6 hours on low.

Why do you sear meatballs before adding them to the slow cooker?

While the meatballs will fully cook in the slow cooker, you always want to sear them first. Searing the meatballs helps them hold their shape in the slow cooker and not become clumped together with the other meatballs.

What to serve with Meatball Soup

  • Cooked egg noodles can be tossed in with the soup before serving
  • The meatballs and soup liquid can be poured over Rosemary Blue Cheese Mashed Potatoes(OMG YUM!!)
  • A sliced baguette can be served alongside the soup for dipping in the soup broth
  • Serve with a Roasted Butternut Squash Spinach Salad for a yummy soup and salad combo!

What else can I make with French Onion Dip Mix?

  • French Onion Dip Tacos
  • Instant Pot French Onion Pot Roast
  • French Onion Chicken Pasta

FAQs

How do you deepen the flavor of French onion soup? ›

Worcestershire sauce – it's a good idea to add 1 ts to the soup if you're using chicken broth – it will deepen its flavor. Sugar – some add sugar to the onions to speed up the caramelization process.

Why is my French onion soup watery? ›

Sometimes soup just needs to simmer longer to reach the perfect consistency. Check to see if the vegetables are tender, and then taste the broth. If the soup tastes a bit watery, give it more time.

Should French onion soup be thick or thin? ›

Made slightly thicker than most watered down soups because every mouthful NEEDS a slightly thickened texture to compliment the caramelized onions.

Why does French onion soup take so long to cook? ›

Properly caramelizing onions takes easily an hour; kind of no way around it. And homemade stock, if you're going that route, takes time too. Beef stock is classic for this soup, but I often prefer a rich vegetable stock with a few dried mushrooms added to the mix.

What can I add to French onion soup to make it better? ›

To amp up the flavor further, I add a generous amount of white wine, along with aromatic thyme and garlic. Then, I finish it all off with a classic French onion soup essential: toasty baguette topped with melty cheese!

How to doctor up canned French onion soup? ›

Infusing the soup with a richer taste is as easy as quickly sauteing crushed garlic before pouring the soup in. Some soft, buttery garlic sauteed in earthy olive oil is the perfect addition to enrich canned French onion soup.

Why do I get diarrhea after French onion soup? ›

Consuming French Onion Soup, which is traditionally topped with cheese, can result in symptoms like stomach cramps, diarrhea, and nausea in these individuals. Furthermore, individuals with onion intolerance may experience digestive discomfort after consuming French Onion Soup due to the high onion content.

Why do you put baking soda in French onion soup? ›

The caramelized onions for this soup cook more quickly due to a pinch of baking soda but still have that deep, slow-cooked flavor. Topping the soup with hot, cheesy toasts prepared while the soup simmers, eliminates the need to bake the soup in specialty French onion soup bowls.

How to thicken up French onion soup? ›

The easiest way to thicken your French onion soup is with flour. You can also use cornstarch if you don't have any flour. Remember to never add the flour or cornstarch directly to the soup – otherwise you run the risk of it clumping.

Does it matter how you cut onions for French onion soup? ›

Also, cutting pole-to-pole results in more uniformly sized slices, both in width and length. For certain cooking preparations using onions, such as French onion soup (our recipe here), this means more manageable and uniform cooking and browning.

Why do you add flour to French onion soup? ›

Onion soup, at its very essence, is nothing more than onions and water boiled together. Period, done, finished, everything added from that point on is pure opinion. Caramelizing the onions brings out sugars, and makes a more luxurious silky and sweet soup, adding flour gently thickens and provides body.

What is the difference between onion soup and French onion soup? ›

What is the Difference Between Onion Soup and French Onion Soup? French onion soup is always made with beef stock. Other onion soups can be made with chicken, vegetable, or beef stock. Additionally, French onion soup typically contains wine or sherry, which isn't typical or necessary in other onion soups.

What is the etiquette for eating French onion soup? ›

With such a soup, a knife is your friend, not your enemy. Using both the soup spoon and the knife, push the baked cheese against the rim of the cup or bowl and cut it gently with the knife. Once you've broken the cheese barrier, you can use the knife again to nudge bits of cheese onto the spoon.

Why is French onion soup so expensive? ›

First, French onion soup calls for a ton of onions. While onions aren't expensive, there's a lot of labor involved in halving, peeling, and slicing 10, 12, 50, or one billion onions (I don't know how much soup you make).

What time of day is French onion soup eaten? ›

But, to answer the OP, if a French person were to eat onion soup, it would be as the starter course for dinner, so somewhere around 8 or 8:30 PM in Paris, 7 PM in the rest of the northern half of the country, and around 9 PM in the south.

How do you make soup taste stronger? ›

Perk up a Bland Soup With Simple Pantry Staples

Add a splash of vinegar (any kind!), or a squeeze of citrus. Chances are, you could use a little more salt. Go ahead—it's ok. Salt perks up flat flavors and helps balance out bitter-tasting ingredients.

How do you get the depth of flavor in vegetable soup? ›

A squeeze of citrus, a dollop of yogurt or a drizzle of cream, a dusting of cheese or a good chile powder, a sprinkling of some herbs or croutons — all can take a perfectly fine soup into the realm of the delectable. Even a spiral of good olive oil to finish and some coarse sea salt can do wonders.

How do you get the depth of Flavour in vegetable soup? ›

Adding a parmesan cheese rind to the simmering soup infuses it with salty, umami flavor. This is SUCH an easy way to add tons of flavor to soup. Look for parmesan cheese rinds at the cheese counter in your grocery store.
