Hot Spinach Balls & Spicy Mustard Sauce: A Crowd-Pleasing Appetizer

Oh, these spinach balls! I can’t tell you how many holiday parties they’ve saved me from showing up empty-handed. I remember one Christmas Eve in particular, I was running late, stressed, and totally forgot I promised to bring an appetizer. A quick rummage through the freezer, a dash to the oven, and I arrived with a platter of these golden-brown orbs of goodness. Even my spinach-averse cousin devoured them, practically inhaling the spicy mustard sauce. Since then, these little guys have become my go-to for potlucks, game nights, or any occasion that calls for a simple, delicious, and secretly veggie-packed snack.

Ingredients

For the Spicy Russian Mustard:

• 1/3 – 1/2 cup dry mustard
• 1/2 cup white vinegar
• 1/2 cup sugar
• 1 egg yolk

For the Spinach Balls:

• 1 (20 ounce) package frozen spinach, well drained (no liquid left in spinach)
• 3 cups packaged seasoned stuffing mix (I use Pepperidge Farm Stuffing)
• 1 cup parmesan cheese, freshly grated
• 6 eggs, small, beaten
• 3/4 cup soft butter
• 1 tablespoon garlic salt
• 1/2 teaspoon Accent seasoning (optional)
• 1/2 teaspoon pepper
• 1/2 teaspoon thyme
• 1/2 grated small onion
• 1 – 1 1/2 teaspoon hot sauce (optional)

Equipment Needed

• Small bowl
• Small pan
• Large bowl
• Cookie sheet
• Freezer bags

Instructions

1. Prepare the Spicy Russian Mustard: In a small bowl, combine the dry mustard and white vinegar. Cover the bowl tightly and let it stand at room temperature overnight. This allows the mustard to bloom and develop its characteristic sharpness.

2. Simmer the Mustard Sauce: The next day, in a small pan, combine the mustard-vinegar mixture, sugar, and egg yolk. Place the pan over low heat and simmer, stirring constantly, until the sauce thickens slightly. Be careful not to boil the sauce, or the egg yolk may scramble.

3. Chill the Mustard Sauce: Once the sauce has thickened, remove it from the heat and let it cool slightly. Cover the pan and store the mustard sauce in the refrigerator for up to 1 month. Serve the mustard sauce at room temperature for the best flavor.

4. (MOST IMPORTANT) Drain the Spinach: This step is absolutely crucial for the success of the spinach balls. Thaw the frozen spinach completely. Then, squeeze out as much liquid as humanly possible. Use your hands, a clean kitchen towel, or even a potato ricer to extract every last drop. Excess moisture will result in soggy spinach balls that won’t hold their shape.

5. Combine the Ingredients: In a large bowl, combine the well-drained spinach, seasoned stuffing mix, parmesan cheese, beaten eggs, soft butter, garlic salt, Accent seasoning (optional), pepper, thyme, grated onion, and hot sauce (optional).

6. Mix Thoroughly: Mix all the ingredients together very well until everything is evenly distributed and the mixture holds together. This ensures that each spinach ball has a consistent flavor and texture.

7. Form the Spinach Balls: Using your hands, roll the spinach mixture into balls that are approximately 1 to 1.5 inches in diameter.

8. Freeze the Spinach Balls: Place the formed spinach balls on a cookie sheet lined with parchment paper or a silicone baking mat. Place the cookie sheet in the freezer and freeze the spinach balls until they are solid. This usually takes several hours.

9. Store the Frozen Spinach Balls: Once the spinach balls are frozen solid, transfer them to a freezer bag or airtight container. Store them in the freezer until needed. They can be stored for several months.

10. Bake the Spinach Balls: When you’re ready to bake the spinach balls, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).

11. Bake Until Golden: Place the frozen spinach balls on a cookie sheet and bake for 15-25 minutes, or until they are golden brown and firm to the touch.

12. Check for Doneness: After 15 minutes, check the spinach balls to see if they are done. Ovens vary, so cooking times may need to be adjusted. The spinach balls should be firm when touched. If they are still soft, cook them for a few minutes longer.

Expert Tips & Tricks

• Draining is Key: I cannot emphasize enough how important it is to thoroughly drain the spinach. If you’re using a kitchen towel, wring it out over the sink until no more water comes out.
• Room Temperature Butter: Softening the butter is essential for easy mixing. Let it sit at room temperature for about 30 minutes before starting the recipe. You can also microwave it in short bursts, but be careful not to melt it.
• Spice it Up: Feel free to adjust the amount of hot sauce to your liking. If you prefer a milder flavor, omit it altogether.
• Cheese Variations: While parmesan is classic, you can experiment with other cheeses like asiago, romano, or even a blend of Italian cheeses.
• Make Ahead: The spinach balls can be assembled and frozen well in advance. This makes them perfect for entertaining.
• Stuffing Mix Substitute: If you don’t have seasoned stuffing mix, you can use plain breadcrumbs and add your own herbs and spices like sage, rosemary, and garlic powder.
• Mustard Shortcut: While the overnight soak for the mustard is ideal, you can get away with a shorter soaking time (a few hours) in a pinch. The flavor will be slightly less intense.

Serving & Storage Suggestions

Serve the hot spinach balls immediately after baking with the spicy Russian mustard sauce on the side for dipping. They are also delicious served with other dipping sauces like ranch dressing, honey mustard, or a creamy dill sauce.

Leftover spinach balls can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake them in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) for about 10 minutes, or until heated through. You can also reheat them in the microwave, but they may become slightly softer.

Frozen spinach balls can be stored in the freezer for up to 3 months.

FAQs (Frequently Asked Questions)

Q: Can I make the spinach balls ahead of time and freeze them?
A: Absolutely! In fact, this is a great way to prepare for a party or gathering. Just follow the recipe up to the freezing step, and then bake them directly from frozen when you’re ready to serve.

Q: What can I use instead of stuffing mix?
A: If you don’t have stuffing mix on hand, you can use breadcrumbs or panko. You’ll want to add some extra seasonings like garlic powder, onion powder, and dried herbs to mimic the flavor of the stuffing mix.

Q: How do I prevent the spinach balls from being soggy?
A: The key is to drain the spinach really, really well. Use a clean kitchen towel or cheesecloth to squeeze out as much moisture as possible.

Q: Can I bake these in an air fryer?
A: Yes, you can air fry the spinach balls. Preheat your air fryer to 350 degrees Fahrenheit (175 degrees Celsius) and cook them for about 10-12 minutes, or until golden brown and crispy.

Q: My mustard sauce is too runny. What can I do?
A: If your mustard sauce is too thin, you can thicken it by simmering it over low heat for a few more minutes, stirring constantly. Be careful not to overcook it, or the egg yolk may scramble.
