Ingredients

  • 1 envelope dry onion soup mix
  • 1 lb. shredded process American cheese
  • 3 Tbsp. chopped parsley
  • 2 c. milk
  • 1 can tuna in oil, drained and flaked
  • corn chips

Instructions

  1. Mix the dry onion soup mix and milk in a medium saucepan; heat slowly until just scalded.
  2. Add a small portion of shredded American cheese and stir constantly until melted.
  3. Gradually add the remaining cheese, stirring constantly until each addition is melted before adding more.
  4. Stir in the drained, flaked tuna and chopped parsley.
  5. Pour the mixture into a fondue saucepan and keep warm by partially covering the flame.

Tips & Substitutions

For a creamier texture, try substituting half of the process American cheese with cream cheese. If you want a bit more flavor, consider adding a dash of Worcestershire sauce or hot sauce to the cheese mixture. Use fresh parsley instead of dried for a more vibrant taste. If you don't have corn chips, serve with toasted baguette slices or vegetable sticks as an alternative.

Serving Suggestions

Serve the cheesy tuna onion fondue warm alongside crispy corn chips for dipping. You can also pair it with assorted fresh vegetables like bell peppers and celery sticks for a healthier option. This dish complements well with a light salad or can be enjoyed as a hearty snack while watching a movie.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the fondue in a saucepan over low heat, stirring frequently to restore its creamy consistency. If it thickens, add a splash of milk to loosen it up before serving again.

Frequently Asked Questions

Can I use fresh tuna instead of canned tuna?

Yes, you can use fresh tuna. Just cook it first until it’s flaky, then mix it into the fondue. This will give your dish a fresher flavor and a different texture compared to canned tuna.

Can I prepare this fondue in advance?

While it's best served fresh, you can prepare the cheese mixture ahead of time and store it in the fridge. Just reheat it gently before serving. It may require some extra stirring to regain its smooth texture.

What can I substitute for dry onion soup mix?

You can create a homemade version by mixing onion powder, garlic powder, and dried onions. This will give you a similar flavor profile without the preservatives. Adjust the proportions to suit your taste.
