Full Moon Cafe Chicken Tortilla Soup
I make this Full Moon Cafe Chicken Tortilla Soup whenever I want something that feels like a hug in a bowl — creamy, cheesy, a little smoky, and finished with bright garnishes that keep it lively. It’s straightforward to pull together, but the technique matters: a smooth roux, careful heat control after adding dairy, and a few finishing touches make the difference between decent and memorable.
This version follows the Full Moon Cafe approach: a velvety base built from chicken stock, roux, and a Monterey Jack/cheddar blend, finished with Rotel, jalapeños, and diced chicken. The soup goes from stovetop to table fast, so it’s perfect for weeknights, casual guests, or when you want to use leftover roast chicken and make it feel special.
Below you’ll find the ingredient list, the exact cooking steps, troubleshooting advice, and sensible swaps. I keep my instructions practical and focused — no fluff, just dependable guidance so your pot comes out the way it should every time.
Ingredients at a Glance
- 1 1/2 quarts chicken stock — the soup’s flavorful liquid foundation; use low-sodium if you want more control over salt.
- 1/2 teaspoon white pepper — adds gentle heat without black flecks; subtle and aromatic.
- 1/2 cup butter — for the roux; gives richness and a smooth mouthfeel.
- 1/2 cup flour — combined with butter to thicken the broth into a creamy base.
- 1 cup shredded Monterey Jack and cheddar cheese blend — melts into the soup for body and that classic cheesy flavor.
- 1 pint half and half — lightens and enriches the soup; adds creaminess without being as heavy as cream.
- 2 teaspoons diced jalapeños — for controlled heat and a fresh pepper flavor; seeds removed if you want milder spice.
- 1 10-ounce can Rotel Diced Tomatoes & Green Chilies — gives brightness, acidity, and a mild chile note.
- 1 cup cooked diced chicken (Full Moon Cafe marinates chicken in fajita seasonings) — the protein; use leftover or rotisserie chicken for speed. If you want that Full Moon Cafe edge, a fajita-style marinade is used.
- guacamole to serve — a creamy, cooling garnish that contrasts the warm, cheesy soup.
- shredded cheese blend to serve — extra melty cheese for topping and extra indulgence.
- deep-fried flour tortilla strips to serve — provide crunch and the tortilla-topping signature of a tortilla soup.
Full Moon Cafe Chicken Tortilla Soup Cooking Guide
- In a large stock pot, combine 1 1/2 quarts chicken stock and 1/2 teaspoon white pepper and bring to a boil over medium-high heat.
- Meanwhile, melt 1/2 cup butter in a small pan over medium heat. Add 1/2 cup flour and stir constantly to form a roux; cook over low heat, stirring constantly, until the roux is smooth and thickened.
- Whisk the hot roux into the boiling chicken stock until fully incorporated and the soup thickens slightly. Reduce the heat to low.
- Add 1 cup shredded Monterey Jack and cheddar cheese blend to the pot and stir until the cheese is fully melted and the mixture is smooth.
- Gradually stir in 1 pint half and half, a little at a time, until incorporated and warmed through. Keep the soup at low heat and do not boil after adding the dairy.
- Stir in 2 teaspoons diced jalapeños, the Rotel Diced Tomatoes & Green Chilies, and 1 cup cooked diced chicken. Heat gently until the tomatoes and chicken are warmed through.
- Ladle the soup into bowls and serve each with a dollop of guacamole, additional shredded cheese blend, and deep-fried flour tortilla strips.
Why This Recipe Belongs in Your Rotation
This soup hits multiple notes: it’s quick to make, uses pantry-friendly items (stock, flour, cheese, canned tomatoes), and showcases simple technique for a restaurant-quality result. The roux and gradual dairy addition produce a smooth, stable base that’s forgiving and scalable. It’s the sort of recipe you can batch for a crowd or scale down for a cozy dinner.
Flavor-wise, it balances richness with bright tomato and jalapeño accents, and the garnishes let each eater tailor the bowl. That flexibility—easy swaps, quick assembly, and wide appeal—makes it an everyday contender for weeknights, meal prep, or casual entertaining.
If You’re Out Of…
- Half and half — use whole milk plus a splash of cream if you have it, but keep the soup at low heat to avoid separation.
- Monterey Jack/cheddar blend — use a similar melter such as Colby Jack or a mix of cheddar and a milder melting cheese; avoid hard aged cheddars only, which can be grainy.
- Rotel — substitute a can of diced tomatoes plus a small can of diced green chiles, or add diced tomatoes with a pinch of cayenne for heat.
- Deep-fried tortilla strips — bake thinly sliced tortillas tossed with oil and salt until crisp for a lighter alternative.
- Cooked chicken — rotisserie chicken, shredded leftover roast, or quickly cooked diced chicken breast all work fine; keep pieces bite-sized.
Before You Start: Equipment
Gather these items so the cook goes smoothly:
- Large stock pot — you need space to whisk in the roux and stir in dairy.
- Small skillet or saucepan — for making the roux.
- Whisk — to incorporate the roux into the hot stock without lumps.
- Spoon or heatproof spatula — for stirring in cheese and chicken.
- Sharp knife and cutting board — for dicing chicken and jalapeños if not pre-diced.
- Ladle and bowls — for serving with garnishes.
Watch Outs & How to Fix
Several common issues come up with creamy, cheese-forward soups. Here’s what to watch for and how to handle each one.
- Creamy base lumps after adding roux — if you see lumps, immediately whisk vigorously; if lumps persist, strain the soup through a fine mesh sieve into a clean pot and whisk to smooth.
- Cheese becomes grainy or separates — cheese can seize if the heat is too high or if it’s added all at once. Keep heat low and add cheese gradually, stirring until melted. If it still splits, take the pot off heat and whisk in a tablespoon of warm stock or half-and-half to help emulsify.
- Soup too thin — simmer gently (do not boil) to reduce and thicken, or whisk a small slurry of equal parts flour and water, cook briefly in a pan, then whisk into the soup.
- Soup too thick — thin with a little hot chicken stock, a splash of milk, or hot water until you reach the desired consistency.
- Too salty — add unsalted stock or a bit of acid (lime juice) to balance; add a peeled, raw potato and simmer briefly to absorb salt (remove potato before serving).
- Spicy enough but lacks brightness — finish with a squeeze of lime or a few dashes of hot sauce or add fresh cilantro if you like herbs.
Better Choices & Swaps
Make adjustments based on dietary needs, pantry status, or flavor preference.
- Dairy-free — use a full-bodied unsweetened non-dairy creamer like cashew-based cream, and choose a dairy-free cheese alternative that melts well.
- Cheese — choose cheeses labeled “good melters”: young cheddar, Monterey Jack, Colby; avoid highly aged or crumbly cheeses for the body of the soup.
- Chicken — for a smoky note, use chicken that’s been grilled or charred slightly; for speed, shred rotisserie chicken.
- Spice level — increase diced jalapeños or add a diced serrano for more heat; reduce or omit to keep it mild.
- Tortilla garnish — substitute crisped corn tortillas for a corn-forward crunch if you prefer.
Pro Tips & Notes
Roux and dairy handling
Make the roux gently. Cook it over low heat until it’s smooth and slightly thickened—you’re only aiming for a thickener, not a deeply flavored brown roux. When you whisk the hot roux into boiling stock, do it in a steady stream and whisk constantly to prevent lumps. After the cheese and half and half go in, keep the pot on low and never boil. Boiling can separate the dairy and create a greasy layer.
Cheese melting
Grate your cheese fresh from a block if you can. Pre-shredded cheese often contains anti-caking agents that can affect melting. Add the cheese in small handfuls, stirring until each addition is fully melted before adding more.
Finishing touches
Garnishes matter. A dollop of guacamole adds creaminess and a cool contrast. Extra shredded cheese gives indulgence. Crisp tortilla strips add necessary texture. Serve these on the side so everyone can top their bowl how they like.
Shelf Life & Storage
Store leftovers in airtight containers in the refrigerator for up to 3–4 days. Reheat gently over low heat, adding a splash of stock or water if needed to restore consistency. Do not boil when reheating; instead, warm slowly and stir often to keep the dairy stable.
For longer storage, freeze in portions without the crunchy tortilla strips and without guacamole. Freeze up to 2 months. Thaw overnight in the refrigerator and reheat gently. Note that texture of dairy-forward soups can change after freezing; gentle reheating and brief whisking usually restores a good consistency.
Helpful Q&A
Can I make this soup vegetarian?
Swap chicken stock for a robust vegetable stock and omit the chicken. Add extra beans, roasted vegetables, or plant-based “chicken” crumbles for body. Use a dairy or non-dairy cheese alternative if you want it fully vegetarian and dairy-free.
How can I make it less rich?
Use a mix of low-fat milk and a smaller amount of half and half, reduce the cheese slightly, and choose baked tortilla chips instead of deep-fried strips.
Can I prepare parts ahead?
Yes. Make the roux and store it refrigerated for a day; warm it gently and whisk into heated stock when ready. Cook and dice the chicken ahead of time, and keep garnishes separate until serving.
Why is my soup grainy?
Graininess usually comes from over-heated cheese or cheese added too quickly. Keep heat low and add cheese gradually. If it’s already grainy, remove from heat and whisk in a small amount of warm liquid to help smooth it.
